With Original Scabbard From my personal collection today I propose you a piece that reluctantly I have to give up is an original : Swiss Army STGW 57 Bayonet With Original Scabbard . Knife bayonet for use on the renowned 7.5 mm. Sturmgewehr 57 selective-fire rifle (the Rolls Royce of selective-fire rifles), made by the firm Schweizerische Industrie-Gesellschaft (S.I.G.). The Stgw. 57 had a very long service life, remaining in production from 1958–1983. As the low serial number suggests, this is an early example. The "W + F" mark indicates assembly by Waffenfabrik Bern , while "W" above the serial number " 393548 " identifying the blade supplier as Wenger. HERE FEATURES : Blade Length : 240 mm Overall Length : 368 Muzzle Ring Diameter : 22.2 Markings : Ricasso: stylized "F" over "+W" inside a circle. "W" over " 393548 " , Crosspiece: "KV146" , Scabbard: "" superimposed on a starburst inside a circle. "B" over "3015" inside a circle. "K9" inside a circle. To avoid conflict, the Swiss government gave half of the military knife & bayonet blade production quota to Wenger and half to Victorinox. Victorinox acquired Wenger in 2005, however, continues marketing products under both trademarks. S.I.G. produced an export model bayonet to go with export versions of the Stgw. 57. The only significant customer was Chile, who purchased 14,500 rifles chambered for the 7.62 mm. NATO cartridge. The 510–4 export bayonet differs from the domestic Stgw. 57 bayonet in minor details.
