Looks like the pattern welded(?) tubes experienced at least 4(with the most recent lighted pic) sets of proof with the first possibly being Bohemian with the right tube at 16.3mm and the left tube at 16.4mm(might be Belgian?). 16.3mm and 16.4mm seem out of the 20 bore range or are just on the edge. Are there any marks forward of the flats?(Answered by the lighted pic). Then a set of London proofs which most have been worn off. Then the "Crown" over "BP" with "shot" for Birmingham 1904-1925 and "Crown" over "BNP" with "950 BAR" Birmingham 1989-2005. A better pic of the crossed scepters adjacent to the "crown" over "R" will probably yield a data. A puzzle I must say.
Kind Regards,
