No. The Owl's head was the logo of the Iver Johnson company. You MAY see a marking such as .38 S&W CTG- but that marking is the caliber- the revolver shoots a .38 Smith & Wesson cartridge (not a .38 Special). ALL guns that shot THAT cartridge were marked .38 S&W, no matter who made the gun. Smith & Wesson owned the name of the cartridge- they invented it.
The .32 S&W cartridge (also known as the .32 S&W Short) was introduced in 1878 for Smith & Wesson pocket revolvers. It was originally designed as a black powder cartridge. The .32 S&W was offered to the public as a light defense cartridge for "card table" distances.
