Notes: Stock was a machine tool manufacturer.

"Franz Stock Maschinenbau und Werkzeugfabrik of Berlin made pistols patented by Walter Decker in 1915-18. Production lasted from 1923 to the early 1930s. The guns were well made, in .22LR, 6.35mm Auto and 7.65mm Auto chamberings, the patented features being the assembly of the breech block and the magazine safety. The Stock was a fixed-barrel blowback with an enveloping slide and a concentric recoil spring; the centre of the slide was open topped, the separate breech block being held by a hook on the rear end of the extractor engaging in a lip on the underside of the slide. A screwed cap in the end of the block, protruding through the rear of the slide, retained the firing pin and spring.
Pistols could be stripped for cleaning simply by lifing the front of the extractor and pressing in the screwed cap; the breech block came loose and could be lifted through the top of the slide." - Hogg & Weeks
