Without knowing what was paid its impossible to know 'how you did' WWII Luger.
If you paid $600, congratulations, you did really well.
If you paid $6,000 condolences, you got taken.
Gotta say I like the gun myself and I would blue it and have fun doing it.
I only say that because it looks as if the gun has been half 'prepped' already in this light.
#'s seem to match so if its just the light playing tricks then I would leave it alone.
BTW ... I'm not a Luger brain lol They will be along shortly.
