PRESTO single Cigar Red pearl & black mottled celluloid handle switchblade knife

Vintage PRESTO single with celluloid scales (handles). The knife was made by the Geo Schrade Knife Co of Bridgeport, CT most likely between 1930 and 1940. It's the only size cigar single made by the company and it measures 3 3/8" closed and 5 15/16" open with brass liners and nickel silver button and safety. The blade is stamped PRESTO PAT PEND-G  on the tang and backside is stamped G SCHRADE in an arch over B'PORT CT. The blade has been sharpened and cleaned with light scratches and some peppering and is about 93% full. The less common Red Pearl & black mottled celluloid scales are very attractive and in good condition with lots of little scratches from handling and a small crack to the button. This knife works well with  blade tip below the liners when closed, Good snap, opens fully and locks with about 1/8" up and down at the tip which is average for these knives. Safety works. G+ condition.
