Alright, so I have recently obtained an Iver Johnson revolver. Above the cylinder says: I.J. TARGET model Model1900 Fitchburg, Mass U.S.A. Serial numbers on the trigger guard and the handle under the grip are 35499. Fires great, had a great time with it too. Any information on this firearm would be great if at all possible. Value? Date made? The pictures should help. If anything else is needed just let me know.
