z PRESTO M2 WWII vintage bone handled automatic knife

PRESTO M2 WWII vintage bone handled automatic knife. This knife was made by the George Schrade Knife Co of Bridgeport, CT sometime between 1930 and 1941. It measures 4 1/8" closed and 7 1/8" open with steel liners, bolsters, bail & button & nickel silver safety. The blade is marked PRESTO over PAT PEND-G on the front and G. SCHRADE over B'PORT, CT on the rear. Blade is 98% full or better with heavy patina and spotting. The scales are very nice with no cracks or chips with lanyard ring (staple). The knife works well with blade tip deep and centered, strong snap and good lockup with about 1/16" movement each way at the tip. Issued to troops during WWII by the US government, likely prior to, or early during the war based on the blade stamp. You can really see the age on this one, but great condition. Safety works. VG+ condition.
