Questions on my Navy Luger

[ithacaartist]

At this point, I'm thinking re-blue 1) toggle axle retaining pin, already mentioned 2) bluing appears to be over the damage on the trigger guard 3) not a hint of a halo in sight on the barrel, which 4) looks shinier than the rest of the pistol.

Check with a 10x loupe to see if there are a bazillion little peen marks absolutely everywhere, which would be a sign it has been bead blasted.
