Help ID Markings

[apis mellifera]

I have a 1939 42 with the following markings on the barrel underside:

L to R
8,82 (know this one)
8835 (the SN) suffix t BTW
3 proofs, the bottom one is NP
9 M/M
.752" (which is ~19mm)
13 or 15 tons

The pistol came with a mag marked 2/1001, a marking so rare that I've only ever seen several many.


Hermann G�¶ring presented this pistol to Hitler's American cousin, hence the markings that appear to be inches and tons. I have created a letter of authenticity to prove this. For the sake of discussion, lets say there was another not as rare pistol marked in similarly the exact way (without letter, of course), what do these markings mean and what do they tell us of this pistols journey?

Thanks,
Matt
