Here is my example of one made by Deumer.
Searching for anything relating to, Anton Boos, 934 Stamm. Kp. Pz. Erz. Abt. 7, 3 Kompanie, Panzer-Regiment 2, 16th Panzer-Division (My father)
Very nice! Slightly different in head construction to my example which must lead me to believe my example is not a Deumer?
So where does that leave us then in identification of my example I wonder?
