Pics of my first Parker

[82nd Trooper]

I've read many discussions pertaining to Damascus barrels and this chamber measures 2-3/4" Galazan chamber gauge so if mine were inspected and measured within the specs by a competent individual would AA 1-1/8oz 1145 fps loads be ok to shoot with?

Additionally in 1904 when this gun was made was this individual gun proofed at a certain percentage over theoretical working pressure or an industry standard for shotguns? Were proof pressures different for certain Parker Guns by grades or barrel types i.e. Damascus, Twist, Stub Twist? Would they have take into account smokeless powder and would 1904 smokeless powder be much different from today standard 1-1/8oz loads?

I know this is very inquisitive post but I try to learn and get immersed into things I find interesting.

Many thanks for all your input and how do you use the thank you function that is seen under individuals post?
