I will agree with Mike in his description of the forestock pin.

I have seen similar "damage" on a Jefferey. The new owner turned and turned and turned the "screw" but it would not "come out". Figuring it was stripped, he choose to drive it out with a punch.

Oh' crap Mike, I wish you hadn't said that......my imagination was that it is a .275......But what if it is a .22 H.V. Velox......:):):)
