Hi Mike........welcome to TFF!
What you have is a Iver Johnson Safety Automatic Double-Action Revolver.
They were made in .22 RF, .32 (S&W)CF, and .38 (S&W)CF. It's a double action revolver and was produced in a variety of barrel lengths, with or without exposed hammers, blued or nickle plated. Many, many thousands of these were made between 1893 and 1950.
They were a pretty inexpensive revolver......in 1902, Sears Roebuck had them listed in their catalog at $3.10.
