I have a HW35 .22 that is about 25 years old. I removed the stock years ago and stored the gun. One of my kids at one point played with just the stock and somehow it has been lost over the years. So I have the rest of the gun including the screws but need a stock. It has as far as I know only had half a tin of pelets through it and has never been dissmantled. I fitted a new breech washer (got from ) last week as the orginal had perished. So I need a stock and ideally convert to .177 or swop it. Is it worth it or should I just sell what I have.
