Bbman, Bobby, has done lots of beautiful restocking and checkering jobs on Foxes. He was about it long before SDH created his beauties, albeit without the publicity.
IMHO, there is a grace and a subtle beauty in the receiver of the Fox. It is smaller, for gauge, than most all the others, and it's reliability, as a basis for a custom gun, is unquestionable. Jim Carmichael said it best many years ago. He wrote something that compared a lesser engraved Fox with a "lush maiden, shed of her arrayment", and how the lower grades needed no help from engraving or inlays to accentuate it's lines.
