The Winchester Model 5. Winchester Repeating Arms Company in 1. For many years it was the premier smallbore match rifle in the United States, if not the world. Known as the King of the. Model 5. 2 has been called by Field Stream one of the 5. Winchester historian Herbert Houze perfection in design. However, by the 1. World War I era design was showing its age and had given way in top level competition to newer match rifles from Walther and Anschtz the costly to produce Model 5. US Repeating Arms took over the manufacture of Winchester rifles from Olin Corporation in 1. OriginseditDuring World War I Winchesters management determined that production of the Model 1. Single Shot would not be resumed in centerfire chamberings after the war, nor in. Winder musket after existing Army training rifle contracts were fulfilled or cancelled. A new. 2. 2 would therefore be needed for the then very popular sport of target shooting Winchester reasoned that returning soldiers would be drawn to the bolt action design with which they had become familiar. The rifle to be designated the Model 5. It was initially hoped that the Army could be persuaded to buy a bolt action smallbore training rifle in addition to or in place of its existing contracts for Model 1. Yet despite the outward appearance of its early versions, the Model 5. Army only purchased 5. DevelopmenteditIn February 1. Thomas Crosley Johnson and Frank Burton to begin work on the new match rifle. Johnson had more experience with bolt actions than most at Winchester which was then primarily a maker of lever and pump action firearms, having superintended production of the P 1. M1. 91. 7 Enfield, as well as having designed a series of prototype military rifles known as Models A through D. 2 Johnson quickly obtained approval for a receiver based closely on that of the Model D, together with a barrel adapted from the. Model 1. 88. 5. The stock from the receiver back was modeled on that of the Model D, which in turn had been derived from the Model 1. Winchester Lee but incorporated a forearm based on a custom Single Shot target stock designed in 1. Winchesters house marksman, Capt. Albert F. Laudensack. 3With the externals settled, Johnson and Burton turned to developing the action for what was now Experimental Design No. Each built a prototype of his own design in Winchesters Model Shop, both at this stage still single shot. In the fall of 1. Johnsons nor Burtons original bolts would work with a magazine feed, but a combination incorporating elements of both proved highly satisfactory. A finalized repeater prototype was made in April 1. Washington where it was evaluated by Lt. Col. Townsend Whelen of the General Staff, Director of Civilian Marksmanship Maj. Richard La. Garde, and Gen. Fred Phillips of the National Rifle Association, who were enthusiastic although guarded about the prospects of a Government contract. Whelen further recommended that pre production samples be rushed out in time for the National Matches 1 at Caldwell, New Jersey that August. Six G2. 2R prototypes were readied, and equipped five individual event winners and the victorious U. S. Dewar Cup team the new Winchester was the talk of the tournament. Accordingly, full production as Model 5. September 1. 91. 9 and commenced in April 1. P 1. 4M1. 91. 7 Enfield. 5. The original Model 5. The Model 5. 2 was a non rotating, rear locked bolt action design. The Model D derived receiver was cylindrical, bored and machined from a forged billet, and of substantial thickness. The bolts dual locking lugs were part of the rotating bolt handle collar, which provided a camming action to seal the breech on closing and extract the spent case on opening. The bolt itself was undercut for the forward third of its length and rode on polished flats a projecting lug at the front edge caught the top cartridge in the magazine. The bolt face was rebated so as to surround the case rim, and was chamfered to fit the recessed receiver ring. Dual opposed sprung claw extractors were inlet into the sides of the bolt, providing controlled cartridge feed. A fixed blade type ejector was located at the rear of the loading platform. The original Johnson trigger mechanism, a two stage or compound motion military type derived, again, from his Model D, made use of a horizontal sear pivoted from the front the trigger fit vertically through a pinned mortise in the sear and was shaped at the top so as to cam against the underside of the bolt and depress the assembly, releasing the firing pin it was a cock on closing design. The one piece striker terminated in a Springfield like knurled cocking piece. The wing safety was mounted on the left side of the receiver when engaged it physically blocked the cocking piece and cammed it slightly rearward, disengaging the trigger linkage. Production historyeditThe Model 5. These changes were not systematic improvements to the action, stock and so on were made on an ad hoc basis, and it is clearer to treat these alterations so separated rather than as models. Note on serial numbers and sub model or Style letter designators It was Winchesters practice to stamp each receiver with its serial number after milling and preliminary polishing, often weeks or months before the rifle was actually assembled. Accordingly, the alphabetic SN suffixes A, B, C and D were applied specifically to changes to the receiver forging itself, originally as an aid to factory workers not to new designs of stock, furniture or even trigger mechanism if no change to the receiver was required. Other design changes might coincide in time with a receiver submodel, or first appear in the same catalog many commentators have been confused by this, talking about such things as the Model 5. B stock which, strictly speaking, did not exist. From beginning to end the barrels were marked Winchester Model 5. Winchester catalogs and advertising literature did not mention letter designators until the 1. Notwithstanding the foregoing, the Model 5. D represented a comprehensive upgrade of the entire rifle. Speed Lock 1. 93. Frank Burton replaced Johnsons military style compound motion trigger, hung from the sear, with a new trigger with a low pivot and rear sear notch, reducing trigger travel by 7. In addition, Burton redesigned the firing pin so as to reduce its travel from approximately. At this time the original models knurled cocking piece disappeared, replaced by a short trapezoidal boss. This and all subsequent M5. Mauser. Burton carefully designed the Speed Lock to fit the existing receiver and bolt body without modification. Winchester for some years offered a conversion kit for older slowlock 5. Model 5. 2A 1. 93. Killers at LargeEl Depredador of Ciudad Juarez 1. Since August, 1. 99. Mexican Federales have been baffled by the growing number of girls and young women appearing dead in the outskirts of Ciudad Juarez a border town next to El Paso with a population of 2 million. The numbers of dead vary according to the source. Here at the Archives we believe there have been at least 1. Juarez since 1. 99. Of these, most have been killed by pimps, drug dealers, husbands and boyfriends. However, at least a third of the deaths seem to be unexplained and possibly the tally of one or more serial killers. Possible Colombian Child Killer 5. Authorities in Colombia, fearing they might have a serial child killer on the loose, have created a special task force to hunt down the suspected maniac. In the past five years fifty five bodies have been discovered, many of them in mass graves, some showing signs of torture and mutilation. We fear that there could be a serial killer, or a group of murderers on the loose, said General Rosso Jose Serrano, Colombias police chief. The bodies of the children are all similarly mutilated, they were buried with hands tied and have organs missing. The killings first caught the public attention last November, when a total of 2. Pereira, 1. 10 miles from the capital, Bogota. Victims have also been discovered in 1. Hundreds more young boys have been reported missing by their families in the past couple of years. The most popular theory among Colombians is that the children were the victims of a Satanic sect. Satanism is said to be widely practised in the Pereira region, and the police have long suspected that children were being snatched off the street to be used in rituals. The police are also exploring suggestions that the children could be the victims of an organ smuggling or a group of pedophiles. Some believe the police themselves are responsible for the killings. It has been known that policemen to take part in paramilitary groups that kidnap and kill homeless people, prostitutes and street children. Many of the victims were living on the streets and making money by begging. The Green River Killer 4. The most prolific unidentified killer of the Archives. The Green River Killer tallied forty nine kills between 1. Seattle Tacoma area. Its believed that the killer is a white, middle aged male. During his two year rampage he enjoyed leaving his victims near the banks of the Green River outside Seattle, thus explaining his moniker. All his victims have been women. He prefers prostitutes, but will kill a runaway or a hitchhiker in a pinch. Some believe that the killer might have died, moved away, was incarcerated, institutionalized, or perhaps just retired. As of August 1. 98. San Diego where he has already bagged ten more women. Twin Cities Killer 3. No one wants to admit it but evidence points to the existence of one or several serial killers working the streets of Minneapolis and St. Paul. From 1. 98. Twin Cities. Most of them were prostitutes in their twenties and thirties. Several were mutilated, dismembered, and sometimes even decapitated. Three scenarios have been posited to explain the growing list of dead. One there is a number of serial killers preying on prostitues and drug users. Two there is one or more serial killers and several murderers who have killed once or twice. Three there is a number of nonserial killers hunting Twin Cities prostitutes. Whatever the case, 3. The I 4. 5 Killers 3. Over that last three decades the FBI has chronicled at least 3. Interstate 4. 5 along the 5. Houston and Galveston in Texas. The latest victim was discoveredin early 1. The dog came up with a bone, and then the boy saw a skull. Nearby, the police later would find earrings, shreds of clothing and a belt tied around a tree. Investigators believe the killer used it to bind the young woman while she was sexually assaulted. Now, for the first time since the first victims corpse was discovered in 1. But early indications are not good for those who hoped it could be brought to an end by finding one serial killer who could be captured and put behind bars. It appears that there may be multiple serial killers, said Don K. Clark, special agent in charge of the FBIs Houston division. If that suspicion proves true and investigators caution that they remain far from bringing charges in these crimes then the bizarre pattern of killings along I 4. Police now worry that for nearly three decades this stretch of coastal plain has served as a hunting ground for any number of murderers. Over time, it appears to police, the killers have come and gone but shared in common the site they selected to find their victims or to dump the bodies of people killed elsewhere. In fact, the bayous lined with longleaf pine, beech and live oaks appear to have served as a dumping ground not only for local killers but also for Houstons predators. The refineries and ports draw transients. The small towns and country roads have proved easy places to hunt victims. The patchwork of jurisdictions makes it easy to cloak activities simply by crossing the city limits. The victims in the I 4. The investigation took an important turn after several particularly horrific and well publicized crimes in 1. First, Laura Smither, 1. Jessica Lee Cain, 1. I 4. 5. Smithers decapitated body was found in a pond almost three weeks after her disappearance. Cain is still missing. Before Laura Smither and Jessica Cain, each one of us was in his own little world, investigating our own individual cases, and we would have no way of knowing that some fellow we wanted to question in one murder, and had been a top suspect, had already been questioned in a very similar murder just a few miles down the highway, said Lt. Tommy Hansen of the Galveston County Sheriffs Department. Some evidence pointed to a serial killer long ago. Two girls disappeared from the same convenience store in the 1. Four bodies were found between 1. More subtle patterns now are emerging from a computer analysis of the evidence. The victims seem to cluster according to physical type, such that it appears one killer has a preference for short, slim, brown haired women. Another killer seems to have demonstrated distinctive habits in the way he disposes of bodies, investigators said. Stark similarities in several early cases suggest that a serial killer was active in the area in the 1. Further complicating matters, Henry Lee Lucas roamed the Gulf Coast when some of the early I 4. Police have been closely following a suspect who remains at large on the I 4. We know a guy, we know him very well, a guy who has killed before and who had some kind of contact with five of the girls, but all the evidence is circumstantial, said police Lt. Gary D. Ratliff of League City, a town of 5. The unnamed suspect suffered physical injuries in an automobile accident a few years ago and appears to have gone dormant since then, Ratliff said. While that is good news in one sense, his lack of activity makes it less likely he might commit a mistake that would allow him to be caught. March 1. 7, 2. 00. Houston investigators believe there are a least a dozen serial killers living in or around the city, or passing through it on a regular basis. One killer is believed to be responsible for the deaths of at least two girls ages 9 and 1. Another cluster of killings involves at least four women in their late teens and early twenties who dissapeared around the southern Houston and Galvenston area. Between April 1. 99.
