Based on the very limited information given, it appears that you have a .32 Double Action 5th Model, manufactured from 1909 to 1919 with the serial number range from (approximately) 283000 to 327641. The "32 S&W CTG" marking (you spelled out "Smith & Wesson" but I assume it's "S&W" on the barrel) doesn't refer to the gun specifically but to the cartridge that it's chambered for, the .32 S&W, an obsolescent cartridge that began life in 1878 loaded with black powder, but apparently is still available, presumably now loaded with smokeless. Note that this is not the same as the commonly available .32 S&W Long, which shouldn't chamber in the gun and definitely shouldn't be fired even if it does. You shouldn't attempt to fire the gun without having it checked out by a gunsmith, and maybe not even then. Value of these guns ranges from a couple hundred to several hundred dollars, depending on condition.
