KarenS, Welcome to the Forum. Your S&W is called a Hand ejector model ( cylinder swings out to the left to load) and it is a .32 Hand Ejector Model of 1903, 5th change, made approximately 1915.
Post a photo, if possible, and we can tell you more about what you have. Unless it has been cut, your barrel length is probably 3 1/4 in. (Measure from the front ofthe cylinder to the muzzle.) Good Luck, Ed.
