The photos I submitted below will show the details of the gun, particularly is you are able to enlarge it photo. There are carvings/engravings on the rifle tp show type and where it was manufactured. Where there is wood near the distal end of the gun, there is a rubber band to assist with keeping the wood positioned correctly.

43" long; 4-3/4 " wide at the butt; 4-1/4 " wide near the trigger; 1-1/2 " wide near the distal end with the metal loop
