Hi Tamid

Thank you

If you look next to the number 411 on the pic above you can see MacNaughton stamped real faint spelled correctly. Its hard to see. I assume that was done by the proof house? I should have mentioned that in the original post.

I looked at my WC Scott hammergun, the proof marks are on the barrels and not on the flats on that gun too. Wouldn't you think it makes more sense to use the barrel flats?
