I was at the Chantilly show this Summer and a couple of fellows showed up at the table with one about like this only with fresh red rust in most of the crevasses..there were portions that had NO rust at all and you could tell it was a mint pistol before it was rusted. 1915 DWM. A good friend offered to remove the rust with an acid bath so I took him up on it. When I saw it next it was blackned but all the rust was gone. I had to hammer it apart...once I got it all apart I wire brushed every part and inspected it. I had to change out the flat sear spring, the flat mag release spring and the trigger. A couple of links on the mainspring broke off but I didn't have another so I just put it back in. Didn't seem to affect it. Magazine has deep rust on it but it still works..an all matching pistol too!
It's completely in the white now but I shot 100 rounds thru it with no problems. for a $50 Luger it's a good shooter!
