Gentlemen, I believe the barrel flats have both London and Birmingham proof marks. The four original proof marks from London on the inner row of each barrel and the Birmingham re-proof marks in the outer row.



I do not have a pic showing the action flat stamps and I have not yet heard back from Purdey's.

Toby, isn't there about the same amount of reveal from the rib to the top of the breech face on this subject gun and the b-i-w gun from Drake's that skeettx posted the pic of?
