1/12/21 - This is an excellent example of a Smith & Wesson Model 18 .22 Combat Masterpiece, made in the late 1950s. The original finish rates at about 98% with a roll mark on the cylinder, and minor high edge wear otherwise. There's also a hint of surface rust on the trigger guard, but possible it would clean off. Mint bore and excellent grips. C&R eligible. Four inch barrel. From Wikipedia: "The Smith & Wesson Model 18 (or the 22 Combat Masterpiece) was built on S&W's "K" Frame, (Smith & Wesson's designation for 'medium frame' firearms.) It was a tapered, 4-inch-barreled, double-action revolver, with adjustable open sights, chambered for the .22 long rifle. Many believe the Model 18 was designed as a training weapon for law enforcement officials and others who primarily carried Model 10's, 15's and 19's-.38 Special and .357 caliber revolvers. The Model 18 (like the Model 17) operates and handles in a similar fashion to these law enforcement models of the day; and closely shares the size, weight, grips, internal mechanism, and operation of several popular "K" framed revolvers."
