Hoping someone here can help me out a bit. I found a J.C. Higgins 16 gauge bolt action ( model 583.8 ) and pretty much made a "spur of the moment" purchase while not knowing much of anything about the gun. Get it home and break it down for a good cleaning only to notice something was definitely wrong. Couldn't for the life of me figure out how the gun could possibly transfer a shell from the tube to the receiver. Long story short, it can't. In the diagram below, I believe I'm missing 7A, 7B, 7C, and 7D. Although, I believe the part I have marked as 7X is there. Anyone know if 7X and 7D are able to separate? This is the best diagram I could find but it is not exactly like my gun, mine does not have a place to put part 36 (nowhere for screws 35 to go) and my part 34 looks quite different. Other than Numrich who is sold out, anybody know where else these parts could be obtained? Thanks in advance for your help.
