Schrade Walden Small Black double 745B vintage automatic knife

Schrade Walden Small Black double 745B vintage automatic knife. Measures 2 7/8" closed and just under 6 inches with both blades open with brass liners made in Walden, NY between 1946 and 1956. Both blades are full and retain all of the original factory finish! Main blade stamped SCHRADE WALDEN NY USA and no markings on the small blade. The black celluloid scales are in nice condition with some marks from handling. The knife works well with  both blade tips below the liners when closed, good snap and good lockup with a little up and down at the tip of the large blade. The small blade does have kickback as most do, but locks great when in the full open position. Both safeties work. EX+ condition.
