Alu POLIZEI buckle - unknown maker mark .. ?

[Winkelman]

A friend came to show me this alu Polizei buckle today , with a curious marking , can't find it anywhere .
I forgot to take pictures of the front , but if anyone could help me with who this maker is , I could at least start the research from there .
Many thanks in advance .. !

Thank you for the info .. !

Sofar , it helped me find 1 RAD officers buckle with indeed a similar marking , but no others yet .
All are the " regular " Dr. F. & Co letters , and none are to be found on Polizei .
I think my friend should be pleased with this interesting find ..

Great RAD officers. First one I have seen from Dr. F. Here is a rare pebbled DAF with the same mark.

Thanks - here is a picture of the front .
As you can see , the pebbling ( especially directly around the circle ) is quite uneven .
This had me worried when I first saw the buckle ..

Found one more - on an Infantry Assault Badge ..
