This is a very neat Iver Johnson and Cycle Works 22lr 8 shot revolver. The finish is worn and sanded, so I'm not sure if it was blued or what type of finish it actually originally had. The hammer no longer locks back to fire as single action but the double action does still work. Meaning that you can squeeze the trigger and the hammer will come back, cylinder rotate, and hammer will fall. The cylinder is loose even when holding the trigger. It does lock, but not tight. Over all this is a very neat and very old gun. But I am not sure of the exact age.
