I have a friend who owns a very old gallery gun. checking on the internet apparently these little rifles were manufactured specifically to be used as target rifles for indoor matches. it is chambered for 22 short only and has what could best be described as a partial semi auto single shot. it is a spring assisted blowback type of action, when fired the case is ejected and the bolt engages a hold open lever. the bolt is manually released by the lever after the shooter inserts another cartridge into the breech. rollmarks on the barrel identify it as an angiers per herstal-belgium breve patented jan 12 1909 cal 22, as best I can read it. it isn't worth very much as a collector, but it could make a nice little target or rodent rifle that doesn't bother the neighbors because it is so quiet. I need to locate some bolt parts for it which have been lost over the years. the barrel and stock are in decent condition, but it isn't a mint museum piece. I tried western gun parts and they had no answer for me , so any help or info would be much appreciated.
