Anyone recognize this case coloring?

[Bruce Day]

I am not aware that the Del Grego shop ever did case coloring by any method. They neither had the room, equipment or expertise.

I am aware that the Del Grego gunsmithing ship would strip frames, polish the metal , and take metal parts to be color case hardened to an industry shop in the Ilion area which did that type of work for a variety of industries in the area. I have no direct knowledge of the above but was told this by the Del Grego shop. Thus when the shop says or implies “we did” it’s more accurate that “ we took it to ——-“.

My knowledge dates from the 1980’s on. I do not know what contractor or industrial shop did the Del Grego requested case color work in the 1950’s to the 70’s. I don’t know the name of the shop but was told by Lawrence that it was a couple miles from their home workshop.
