Jason, you came to a forum that specilizes in Lugers, and that has seen many, many VERY well restored guns, so YES, we are going to have some doubt on a very nice gun. Not sure why you feel you are being crucified or tormented? (my words since you didn't say that, but you made several comments about you knew your gun would be suspect). Well hell yeah, there are a couple of guys in the Pennsylvania area that re-do guns and match them up with two matching magazines (which is rare in itself), so yes, we are very careful.
Take a bright light, shine it on the finish, it should look slightly rusty colored, deep into the bluing. This is CORRECT, it is rust, its called patina and that is what a 60+ yr old gun should look like.
As an aside, I never saw what kind of luger it was until I looked close at the pictures. for us non-mauser guys, its good to say 1941 byf mauser, blah, blah
