PRESTO M2 style Scout Black metal painted vintage automatic knife

Vintage PRESTO paratrooper style switchblade made by the Geo Schrade Knife Co of Bridgeport, CT sometime between 1929 and 1956. It is the same size and configuration as the M2 paratrooper switchblades used during WWII. It is possible that some of these with metal handles were actually issued during the war, but I haven't found proof of that. The knife measures 4 1/8" closed and just over 7 inches open with steel liners, button, safety and lanyard ring. The blade is stamped PRESTO over MADE IN USA on the front and GEO SCHRADE over BRIDGEPORT, over CONN on the rear. The blade is mostly full and shiny with some light scratches. The painted metal scales are missing some paint from use/carry, but good condition overall. The blade tip seats deep, strong snap and good lockup with less than 1/16" movement at the tip. Safety works. VG+ condition.
