GHE Side by side
 

Markings on my just received Parker GHE. On the lug 1 1/2 with a small B. On the left side of water table 8 over capital D. Large 3 with smaller 13. On right side water table JG in oval over that an x or *. Serial number 158764. Barrels appear to be relatively pit free in fact I can't discern any. It is in fair shape and was just beautiful when new I imagine. Ejectors work fine, and overall I think I would like to restore it, will need ribs re- layed at a minimum.

Pictures would help. Several good gunsmiths on here can give you advice on the restoration issues
