SCHRADE WALDEN NY USA #151 Fishtail Black Stagged vintage automatic knife w bolsters

Schrade Walden fishtail switchblade knife with black jigged synthetic handles made in Walden, NY sometime between 1946 and 1956 and designated the model #150. It measures 4 inches closed and 7.25 inches open with brass liners and nickel silver bolsters, button & safety. The clip blade is 99% full or better and shiny and is marked SCHRADE WALDEN NY USA. The black stagged (imitation jigged bone) scales are in very good condition with no shrinkage and no cracks. The knife works well with blade tip seating deep and good snap, but does not lock open properly. It stays open, but doesn't lock so you can push it closed without pressing the button. You wouldn't know anything was wrong unless you push on the blade when open. Could be repaired if desired. Safety works. VG+ condition.
