Edgemaster Fishtail Blue Sparkle vintage switchblade knife

Edgemaster fishtail with Blue Sparkle synthetic scales made by the Federal Knife Co of Providence, RI in the late 40s, or early 1950s. This knife was designated the model #301 and measures 4 inches closed and 7 1/8" open with brass liners and steel button and safety. The blade is mostly full with a lot of scratches from sharpening and is stamped Edgemaster USA. The Blue Sparkle scales are in great condition with minimal shrinkage and appear to have been repinned at some time. The knife functions good with blade tip seating deep, good snap and locks open with about 1/4" up and down at the tip. Safety works marginally. G- condition.
