looking to buy a 62A gallery Clamp and Spring, can anybody help me out?  

Mike Bishop had some for sale a couple years ago.  I looked at his ad’s on Guns Int’l and he didn’t have any listed.  You might try to send him a note via Gun’s Intl and see if he has any.

And there are two currently listed on ebay.  Search “Winchester Gallery”.

Good luck.
