These are matched to all other ser# on the gun, were Damascus barrels used through 1935?
This is a Field Grade gun. The markings on the bottom of both barrels are; H, next to that 4 over 6, BH next to what appears to be a 17, and either an R or B with a D next to it. Iíve searched all I can I canít find what these mean. I would really appreciate help with this. Thank you
