Sorry for the belated start of Wheelgun Wednesday. Today, we have a couple of revolvers from the late John Nowlin Sr., a gunsmith better known for his semi-pistols and match barrels.
First up is a Smith & Wesson Model 64 modified for Bianchi Cup/NRA Action Pistol competition.
Second is a hard-chromed Smith & Wesson Model 25-2 modified for Bowling Pin shooting. Note that the cylinder has been shortened to reduce the free-bore jump of the projectile from the case mouth to the barrel throat. The underlug is interchangeable. This looks to be an early conversion as Nowlin later offered a “Master Blaster” kit with an expansion chamber compensator.
