J.C. Higgins .22.
I had a customer bring me a .22 single-shot rifle that had been in his father's basement for about 30 years. He asked me to clean it and check it out to be sure it was safe to shoot. The stampings on the rifle are, "J.C. Higgins, Model 101.24, Sears, Roebuck & Co., 22 Short, Long or Long Rifle."
The problem is the bolt won't open and will only move about 1/32 of an inch. This is about as simple as a rifle gets and I am at a total loss as to what could possibly be keeping to bolt from opening.
You'll have to find out who made the rifle for Sears as they didn't make the guns they sold. There is a cross reference section living on some backpages of the Numrich Gun Parts Corporation catalog. After you have determined the identity of the manufacturer, contact us and we may be able to help you. At the moment, we have only a hunch that the bolt could be seriously fouled, or even rusted, shut.
