I agree, I think someone tried to demil it.
It is upside down, as I had to hold the barrel between my knees, holding the flashlight with my left hand and the camera with my right to get the punch mark to show.
Took me 4 tries to get a decent photo.
Now I see the wedge you mentioned. Glad to hear it isn't a problem.
Still no answer at the Freischutz number.
