We need to preserve this for our descendants.
Whatever it is, it has proof marks in the right place. The ejector looks strawed. The sideplate has a number stamped on it. The flat spring behind the sear has a lip on it, like a real Luger. The magazine release has a flat spring under it.
The safety lever is strange. Checkered, not serrated. And cylindrical, not flat. I don't see a spring behind the trigger.
Lots of detail. If I had to guess, I'd say an MGC Modelgun from the 60's. They were very realistic, and functioned exactly like a real Luger, even to loading and ejecting fake cartridges, which contained a primer and a powder charge but only produced a flash, smoke, and a bang. The barrel was blocked so a real cartridge wouldn't fire. And the firing pin was in the chamber, and the primer was in the middle of the 'cartridge'.
I haven't read the thread on Still's forum. Does anyone have the link???
