Manufactured in 1944 to Luftwaffe specifications, chiefly alloy in construction with some steel components. Marked "gpt/ 1944" (Gustav Bittner, Sudetenland) on the frame, with "eagle/SP" proofs, "4" on top of each barrel, "Ln 24483" on the left side of the frame, automatic safety, dual triggers, selector switch and checkered grips.

Very fine, with 75% of the original black anodized finish, with bright edge wear, scattered scratches and mild handling marks. The grips are also very fine, with mild dings. The selector switch does not function/engage, otherwise mechanically very good.
