As far as I concern, Ned, around 5.000 P-06 in 7,65mm and (estimated) 500 P-06 in 9mm - those supposed to be destinated to higher rank officers - were ordered in 1908. You own a Brazilian contract Luger because in the early 70's Brazilian Army sold tho U.S.A. dealers most of the remaining samples in fair condition. Due to the fact that Brazilian contracts were so few, seems that they were produced as civilians, with the same amount of care with the finish and tolerances. The only item I have ever saw mismatched are the grips - often replaced due to wear and moisture.
You know, it is easier to find a good Brazilian contract Luger in U.S.A. than in Brazil... as you may have heard, the political agenda here is to ban any kind of gun fron civilian hands. Fortunately, we have won the referendum that pretended to ban guns AND ammunition. Sadly, NRA did not move a finger to help us... many Lugers - including WWII's were destroyed by anti-gun radicals.
Back to Lugers, it is usual that a Brazilian one bear some pitting. Since they were carried in several revolutions and conflicts, most of them frequently in highly hot areas - soldiers sweating, humid tropical wheather, sand and dust, poor manteinance... in the far country, still today we hear from people who lubricate guns with soy oil, animal grease, among other nightmares...
My Luger (7.65) - numbered 4.176 - is 80%, and is the best I have seen in Brazil. A mint one? Still dreamin about it.
