PRESTO Cigar Jack All Metal single black vintage American switchblade knife

Vintage Presto cigar jack switchblade made by the Geo Schrade Knife Co of Bridgeport, CT sometime between 1935 and 1950 and is not an easy knife to find. The knife measures 3 3/8" closed and 5 15/16 inches open and it has brass liners and steel scales, button and safety. The clip blade is 98% full with light patina and a few tiny spots and is stamped PRESTO over MADE IN USA and the rear is stamped G SCHRADE in an arch over B'PORT, CT. All metal painted (imitation stag) scales (handles) are in good condition with nearly all of the original paint intact. The knife works great with the blade tip deep & centered closed, good snap and very good lockup with about 1/16" movement at the tip. Barely rattles if shaken with blade open. This really is a hard example to find. Safety works. EX condition.
