Appears to be a cast replica of a WW II German police cap eagle with a newer style pin added for attachment.
Searching for anything relating to, Anton Boos, 934 Stamm. Kp. Pz. Erz. Abt. 7, 3 Kompanie, Panzer-Regiment 2, 16th Panzer-Division (My father)
The badge has been modified and painted. With the paint I really can't tell you if it is original. I wish I could tell you more.
It's based upon a police cap badge and the pin is American in style I believe so to answer your question it is a fake cap badge with a non TR method of attachment
Looking for LDO marked EK2s and items relating to U-406.....
It's a wasted trip baby. Nobody said nothing about locking horns with no Tigers.
