Parker 16 Guage Model Questions

[Bindlestiff]

I had a nice 28ga GHE and when I fired the right barrel, I would hear a clear, high pitch ring. I hunted with it and had no problems but one day in the field I noted that the small locking screw on the side of the receiver was lost. I was near my gunsmith's shop so I stopped in and he replaced the screw............ and the ring was gone.

I have no idea why or what may have caused it. It was the only Parker I ever shot that had the ring and when Herb replaced the small screw it was gone.
