This board lays on top of the Crown moulding and miteres to the wall on each side. The plane shown is my English -they were all English- ogee, cyma curve moulding plane I bought at the immense and great Brimfield Flea Market in Brimfield, Ma. in 1980. It makes a 13/16" ogee, which is the same profile, and I mean exactly, used on the interior girts, summer beams and wind braces of the William Haskell House in Gloucester, Ma., 1660. It matches the one on this cupboard, 1750, and I placed it right on the moulding - for the owner to see- on one of the arched panel fireplace Crown mouldings in the Parlor of the Peter Olcott (Double Door Entryway) House built in 1789 in Norwich, Vt. Of course, they were made by the thousands for the colonies for one hundred and fifty years at least ! I've been grateful to help it mould another generations worth of beauty. This is my attempt to inform and help historically interested people truly appreciate the craftsmanship that has been bestowed upon us.
