2.5 grams of Schultze powder
2.6 grams of lead
2.1 grams of Military Flake Powder(I'm assuming "BP" is Blättchenpulver which is usually denoted by "GPB" which with the "Crown" over "N" was in use since July 23rd, 1893)
And you have the "Crown" over "F"(Gothic) which I'm not sure of its origin.
I'll look at the marks a bit closer but the "Crown" over "N" with load data, sometimes service, sometimes proof, was voluntary so I really can't say why the "Eagle Nitro" proof is there except that it was made in 1912 during the rules change and the maker opted for it or the purchaser requested it. Yes, reproof was common as when Nitro proof was law, reproof was probably sold as the "have to have" to be up with the Jones.
I haven't look close but are there any initials on the tubes?
Kind Regards,
