thanks Martin for the addition. Yes I have 6 boxes similiarily marked from the smae manufacturer. All rounds that I am awre of are polished-laquer. Ther was an old gent at a local gun-show that I purchased these through for the sake of my collection only about 10 years ago. 6 boxes for 15.00 US was a fair trade I thought....
what I have been used is the collected brass from a German manufacturer since I do my own re-loading, via Geco 9mm Luger Parabellum, 8.0g Vollmantel-Geschoß, hard to find brass these days, and with the low ebb on primers two years ago it was a total pain to order all over the states and hobby shooting became a rarity in order a couple years ago. The primers situation seems to have been remided now. My feelings is save what you have from the Ww 2 end and not overburden your prize pieces, though I must confess I have a blast shooting off 50-60 rounds at a time with my WW 1 aviators pistol:

Becker & Holländer. Waffenbau Suhl / Selbstlade-Pistole' Beholla' Cal 7.65 D.R.P., with origianl holster. This unit was in some old circualtion with Luftwaffe aircrews until more modern 7.65's took it';s place. The pistol is a dram to shoot and my kids have enjoyed peppering the targets at 25 yds with this littl firearm. In fact I think it is more accurate than the WW 2 9mm's.
The small unit takes the standard 32. autto round just fine, but it does jamm after about 25 or so rounds from time to time. Thourghly cleaned and tuned the thing is showing it's time and it's time to retire the piece before any internal damge occurs....
