Looking at a 1899 16 gauge French gun which was proofed for S and T powders when made, then Reproofed in 1941 with a Nazi nitro proof stamp both, J and N German reproof stamps also on the barrels. I can look up the S and T proof loads but have no idea what it was proofed at in 1941. What was the standard nitro proof the Germans used in 1941 and was it redone in France or in Germany as a war trophy?

Why the reproof I wonder? Chambers are stamped 65. Were many guns reproofed after they were confiscated by the Germans? If only these guns could talk. A French gun, liberated by a German, then liberated again by a GI and brought back the the US. I am trying to steer the new owner away from Wally World factory shells but need to explain to him what the gun was designed to shoot and has been proofed to shoot. Perhaps the best thing is to just tell him what it was proofed for when made but I like to give him both then and the later proof pressure levels.

Proof marks I have are S.2.93_30
T.2.99_30 might be 89 or 99 Damn Nazi overstamp.

I see the T proof was the normale and the S the higher d'epreuve
