I dug this up locally, a 1944 German G43 semi-auto in 8mm Mauser... a lesser known Nazi weapon when you consider the K98, Luger, P38, Mg42 and others. Pretty much, it's a rough copy of the SVT40 as you will see in the gas system. It's also one weapon that was never manufactured by Mauser, 3 German firms made them, Berlin-Lübecker Maschinenfabrik, Wilhelm Gustloff-Werke and Walther. Designed and made late in the war, it never saw the typical enhancements and upgrades the other weapons saw during their service life. Before the war ended, over 400,000 were made and used later by East Germany and other nations, mainly as police weapons.
This example seems to have very low wear and matching numbers with the exception of the magazine, the stock has a penciled number under the nose cap. The bore is bright and shiny. I have no clue if it's a pre '68 import or bringback, as there are no import stamps. I did do a cursory operational test, I loaded 5 rds of Prvi 8mm in it, and let it rip, to my surprise, recoil was fairly low as the gas system negates it some.
A few stock stamps.. it has a laminated stock, like most K98 rifles..
Sights and action.... and no, I didn't alter the photo of the bolt handle, it's a left side cocking knob.
Dust cover, it slides forward to the bolt and covers the action, when fired, it opens up automatically and remains open till closed manually.
And now the gas system....kinda just like an SVT.
And it has a storage space in the butt stock.. it had a manual dated 5.44 written in German, a replacement firing pin and extractor inside.
