Good eve, I am hoping once again to enlist some insightful help in understanding the barrel flat coding on the Bayard that I inherited with the Darne equipped gun I asked about earlier this week.
In an attempt to assimilate all the kind help I received on that thread, and utilizing the Belgian proof info I found on this forum, I am postulating that this is a 12 gauge gun that will take 2.75 " shells. One point of confusion for me is that it appears that the year of origin is 1924, but the controller stamp indicates no earlier than 1937.
I also do not see any information related to pressure rating of the barrels.
Thanks for any thoughts!
