PRESTO Double Red & Green Vintage switchblade knife

Vintage PRESTO double with Red & Green celluloid scales (handles). The knife was made by the Geo Schrade Knife Co of Bridgeport, CT between 1940 and 1956. It's the only size double made by the company and it measures 3 3/8" closed and 7" open with brass liners and nickel silver buttons & safeties. Main blade is stamped PRESTO PAT JAN 30-40 MADE IN USA and the small blade is stamped G SCHRADE in an arch over KNIFE CO in an arch over B'PORT CT. The blades are about 90% full with patina & scratches. The Red & Green celluloid scales are very unusual and in very good condition. The knife works well with large blade tip slightly above liners closed and small blade tip below the liners when closed, Good snap, both blades open fully with no kickback and good lockup with very little movement. Nice example of a vintage American PRESTO double switchblade. Both safeties work. G+ condition.
