Recently I obtained a German heer dagger and did some research on different sites and I still can’t figure out if it’s real or fake.

I can’t take it apart. The pommel is stuck. I used some ”force” but don’t wanna damage it.
The grip is because of this a little bit loose. Probably because you can’t screw the pommel completely onto the blade.
The blade is unmarked and shows some signs of oxidation and stains and I didn’t wanna clean it so fare. But there is hope to make it more shiny. I think the last owner used WD40 to keep the blade ”oiled”

On the hanger I see D.R.G.M

The dagger looks in okay condition but some cleaning will help I guess.

Also some questions from my side.
If this dagger is fake, did they made unmarked fake / replica’s ?
What kind of dagger is this.
Is my Portapee or Hanger real?
And is a Dagger in this condition valuable?

Please see pictures.

Thanks
Marty
