COLONIAL SHUR-SNAP Fishtail 1st Generation Yellow swirl switchblade knife

Vintage COLONIAL SHUR SNAP Fishtail Yellow swirl Early 1st Gen switchblade knife made by the Colonial Knife Co of Providence, RI in the late 1940s designated the model 1800B. You can tell it's 1st gen because of the small flat button and no bolsters. The blade is 100% full with factory finish and is stamped SHUR-SNAP COLONIAL, PROV USA and has some light scuffs/scratches and a little spotting. The Yellow swirl synthetic scales are in very good condition with a little shrinkage along the edges. Knife works great with blade tip deep and centered in the well closed, good snap and good lockup with 1/16" movement at the tip. Rattles slightly if shaken with blade open. Safety works. EX+ condition
