Great lamp. We believe this is the Henry model.
Plug broken so needs new one, clip on plugs are available and easy to install. Actual gun with "H" on oval metal piece inset into faux bone handles. Sides marked "Texas Ranger". Copper tone with fantastic scroll work.
As set gun does not appear to fire but there are 3 screws set into the gun to make the lamp and one may prevent firing. Sits on wood plaque with small holster with 2 set in bullets and 3 other removable ones. Height to socket is 14".
