I believe that observation is only partly correct, Ed. There have been two Wappen on this M95 during the course of its service life, and both have cut into the surface leaving a "ghost." We all have a comfort level when it comes to purchasing a historic object that has passed through so many hands, Kammer, family, and collector, over the span of 115± years. Perhaps I rationalize, but issued military equipment was reissued and repaired. I own several examples of Feldbrauchbar helmets bearing Garnitur stamps. Honestly, I have no problem with it. Perhaps, it was originally issued to IR 87. Who knows?
For me the criteria are rarity, obvious signs of fakery, and price.
Is the helmet original? Yes. Does it have the correct spike (e.g., static or Trichter compatible) for the regiment in question? Yes. Is the Wappen authentic? Yes. Is the furniture (chin strap and kokarden) original and does it fit properly? Yes. Has the Wappen been modified (re-soldered loops or threaded posts) to fit the helmet? No. Has the helmet been modified (extra or enlarged holes) to fit the Wappen? No.
I'm happy with my purchase.
