German Buttons??

[RodneyO]

Hi All,
Could someone please tell me if these buttons are German, WW2? Most are hollow back with pebble grain front and only two have backings.
Thank you,
Rodney

Good morning to you Rodney.
Indeed I confirm you that all your buttons are german from the WW2 period.
For example :
PC&Co stand for Paul Cramer & Co., Lüdenscheid
A&S= Assmann & Söhne, Lüdenscheid
...
Simply could you tell me exactly what's written "DEITENBECK"? Is it corect?

Thank you Christophorus ...
The button with backing is marked R. DEITENBECK and the other one is EXTRA FEIN.
These are on a Czech greatcoat that I bought many many years ago as a WW2 German greatcoat...... ....
The coat is stamped:
B ? & ?
193?
BOSKOVICE
Would the Germans use Czech greatcoats during the war? I was thinking about removing the buttons to keep as extras.

Aloha,
Rodney
