Need help with erkennungsmarke

[j dubbel]

hello

I just got this today and I would like to know if someone knows this panzer regiment and where they were stationed and were they have fought. The erkennungsmarke is a bit bigger then the one`s with 3 holes

Maybe early war?

Panzer-Ersatz-Abteilung 10 - Lexikon der Wehrmacht

Here's a start for some research
