Hi policeluger, I've some small parts, hinges, latches, screws, magazines (not necessarly Luger), etc... that have metal plating that was common in pre 1946 Europe, but are not readily found now??... Actually, probably still very common, but with the aging, and oxidation, that has taken place, it's hard to tell if it's nickel, tin, tin lead, zinc, over copper, etc.... and in what proportions... I need someone with the chemical means, or equipment to inspect and replicate a couple of these finishes... So I can continue on my merry little random never ending quests....
... If you have a go to guy, please let me in on it... I have samples / examples for the tests... but would like them back as they are original and hard to replace... Best to all, til...lat'r.....GT
