Point taken Tom I bow to your superior knowledge on this one. I have never had a Hollenbeck three barrel in my hands but I have studied the old 10 gauge. I thought maybe by putting on a set of 16 doubles high up in the frame, bushing and relocating the firing pins up accordingly, I might buy enough room in the bottom for a 32/40. Underhammer strikers are nothing special to engineer, but then again I have never examined the two guns together. I thought properly done it might be a fitting tribute to the old 10 I figure there isn't enough left of it for a proper restore. PS I am still waiting for the two Elsie receivers to arrive in the mail
