I am trying to repair and partially restore an old .22 lr. It has J.G.A. ZELLA-MEHLIS, GERMANY and the J.G.A. logo circled stamped on top of the barrel, the serial #117904 and .22 long rifle stamped on the side. My friends father recieved it as payment for months of work when he was 15yrs old so approx. 1950. It is missing parts that attach the trigger to the bolt assembly as well as a stock. The stock in the pictures was built by some fool who didnt know what they were doing and I had to break it to get it off. If anyone could please help me determine the exact model, specific name of the parts needed or a drawing with parts breakdown and, any possible sources for these parts or compatible parts. I am confident that I can modify another .22 stock to work so that should not be a problem. This rifle has a huge sentimental value and I am trying to get it in firing condition before he is gone. If at all possible I would like to get it back to original condition but, the monitary value is secondary to the joy it will bring an old man. I appreciate any assistance I could get. Thank you. My PC wont let me upload my photos for some reason but I will very soon.
