PRESTO Fishtail #4000 Coffee & Cream celluloid bolsters vintage automatic knife

Vintage PRESTO Fishtail #4000 Coffee & Cream celluloid automatic knife with bolsters on both ends automatic made by the George Schrade Knife Co of Bridgeport, CT sometime between 1929 and 1940. It measures 4 inches closed and 7 3/16 inches open with brass liners and nickel silver top bolsters & safety and steel bottom bolsters & button. The clip blade is about 95% full and mostly shiny with scratches and some light grinder marks and is stamped PRESTO MADE IN USA on the tang and G. SCHRADE in an arch over B'PORT, CT on the backside. The Coffee & Cream celluloid scales are very attractive with a small piece broken out by center back pin and a few minor imperfections. Works well with blade tip even with liners closed, opens fully and locks with about 3/16" up an down at the tip and some side to side. Does rattle if shaken with blade open. Safety doesn't work well. Good used condition.
