An heirloom Fraser sidelock would be a very special piece! I'm drooling over a best quality boxlock and waiting to see if I can overcome a price tag just a bit beyond my allowance and my general aversion to full pistol grips.
Just noticed this on GI:
http://www.gunsinternational.com/guns-fo...un_id=100658979 If you have not done so long since, consider getting it into the hands of someone who really knows British doubles for a strip, clean & inspection. J.J. Perodeau, co-located with Champlins in Oklahoma, and Kirk Merrington in Texas come to mind; I'm sure there are others, but check first to make sure they are expert gunmakers specializing in British doubles. Free advice and guaranteed worth every penny!
