I have to go with Ron on this one. Some of the photos are a bit dark, showing the blue to be a bit more blackish than it really is. The lines are crisp and clear, halos are present and the overall wear seems to be consistant with age.
The takedown lever looks dark indeed, almost as if it was blued but this can also be a result of reflections (had the same problem trying to photograph pistols with small parts that had no strawing left).
The grips look like late war beech versions to me.
Of course, one has to inspect a pistol up close and personal to be sure, but it looks good to me.
PS: I'd love to see a 'Homer Simpson Commemorative Luger'
