One of these? Mine was bought new about 50 years ago, has been resealed three times and has dropped a chitt pile of critters. Last reseal was just a few years ago. At the reseal the 'smith (local) had an OEM forearm replacing the "square" one I made in high school. He had quite a selection of OEM Benjamin and Sheridan parts. As above, it's going nowhere. Maybe a grandchild will get it.
