Do you mean DelGrego & Son?
Their shop is only a couple minutes away from the Remington plant in Ilion, that would have made a nice stop for you on your recent trip as well as the museum.
PS. I have several Parker's with "full combs" that came from the factory, a particular VH is really fat.
Both guns below are both 12ga VH's on 1 1/2 frames, the gun on the left is from 1928 and the stock is orginal to the gun although it was refinished before I bought it. How's that for a fat comb?
