I am trying to figure out the maker and proofs on a reproofed Birmingham gun. The new nitro proof is 28-70 950 bar. The old proof has 132 Birmingham view mark and 32 with c below in the triangle. It also has the crown over R and a G in a triangle. There is also a S on the brl flats. Rt brl has 13.5 and left brl 13.6 The twist brls have been redone but there is no name on the rib. H & N is on the brl flats. The G in the triangle is on both sides of brl flats and another on the left brl btm, the action flats also has the same on each side of flat. I was told the gun is a Holloway & Naughton but seems to me the gun is too old for that. Any thoughts appreciated.
Thanks,
Dwight
