Fixing cocking mechanism?

[Kevin McCormack]

May be worn or broken ejector sear(s) or (more likely) 100 years of crud built up in the ejector train. Try taking the forend iron out of the wood (carefully!), then soak the entire forend iron assembly in laquer thinner or similar solvent for a couple of days.

DO NOT TRY TO DISASSEMBLE THE EJECTOR MECHANISM!!! This is a job for a Parker-experienced gunsmith only - there are many small parts and some can actually be reinstalled backwards, like the small brass clips on either side of the ejector rails, which will go in but when the forend is put back on the gun, will not work properly, a major PITA after all that work! If thorough cleaning doesn't work, seek professional help. Botched Parker ejector repair jobs are like bad-running vintage Jaguar cars - aggravating and expensive!
