Today my father gave me his mossberg 142k .22 that he bought in 1956. It has'nt been fired in at least 30 years, most definately more. It's been wrapped in a old blanket and stored in a closet. The outside of the barrel has no more blue on it and has a little rust and pits, but the bore and the wood looks good. Now, I've got to figure out how to disassemble it and then clean it. Any tips on how to restore the barrel? And how would I get it registered? Thanks, Wayne
