This illustrates what happens when a Browing T-22 was left in its original salt wood stock for close to 50 years. It is a 1966 year of production. It is not too far gone through considerable damage was done to the barrel, some to the receiver and even more to the aluminum trigger housing and trigger guard. There is a substantial portion of rust pitting above stock line. That is likely what caused a previous owner to dis-mount the stock and try to fix the problem by lining the stock inletting with clear packing tape.
