A JC Higgins .22 all metal co2 revolver. Sold by sears and made in the USA. Definitely not something you see everyday. Belongs to my dad and im positive its older than me. I had it working but its sat a while and leaks now so I'll have to fix it again but it will still shoot. How old is this thing and is there anywhere that sells parts for it or do I need to match seals from something else.
