I cant help you with your gun. It looks as if some fool has drilled holes in the chamber area to render it unusable. If that is the case, I am truly sorry to see it. That was not that old a gun, and I would find it hard to believe there was a safety issue involved with the use of that gun that was serious enough to destroy it. It was a good quality, useful gun for sporting pursuits, not something any criminal would have been interested in.
I believe it is a perfect example of where misguided gun control efforts invariably end. This is where they always end, and where the sponsors of same want their efforts to end.
It is really a shame.

Best,
Ted
