COLONIAL SHUR-SNAP Fishtail Early White vintage switchblade knife

This is an early model made before 1955 by the Colonial Knife co of Providence, RI designated model 1800B. We can date it by the characteristics of small domed button and bolsters. This knife measures 4 inches closed and 7.25 inches open with brass liners and steel bolsters & button. The blade is 100% full with original factory finish and some light scratches, but overall extra nice. The blade is clearly stamped SHUR-SNAP COLONIAL PROV USA. The scales are white synthetic and are in excellent condition with just a bit of shrinkage along the edge. The knife works well, tip below the liners closed, good snap and average lockup with less than 1/8" movement each way at the tip. Knife rattles a little if shaken when open. Nice old 1950s American fishtail switchblade. Safety works. EX+ condition.
