Herb, OH! OOPS...It is my guess, and without a close inspection of the metal etchings, I could not say for sure, I don't think this was put on there with a die at all, but engraved.

There are machinists with computer engravers out there where a copy can be scanned out of a page on a book and neatly engraved, any size you want.
Curvature would not be a factor, nor would the expense of a die.
As for escalating cost concerning the placement of a spurious mark, I would guess it could be as much as a thousand dollars without stretching credulity. Whatever the market would bear in the heat and dim light of your normal gun show.
I suspect that John Sabato or Ron wood or someone else out there in our membership could expound on this subject that is more knowledgeable than myself.

Herb says; strange markings do pop up now and then. Herb, I suppose this is true but not that often and so out of the norm for the stick Eagle. This was pretty much set in stone and one of this variation is wrong in so many ways it would be one of a kind and span a decade of different styles.

I vote you send it to Thor and rub out all traces of this horrible disfigurement.Bring this pistol back to what it once was.
...But then, that's just me. Jerry Burney
