Do you have the box?Model 625-9, 4".
Serial Number DBU33XX.
Your revolver is a Colt Official Police, it's not a S&W product. I suggest reposting your request in the main section of the "Revolver" subforum.I aquired this S+W revolver years ago in a trade. The 4" barrel is marked (Offical Police .38 Special CTG).
