Good evening harrison987 !

Indeed, the correct German spelling of Pik Ass is not Pick Ass. But under some circumstances, one could write it like it is written, since there is nearly no difference in the pronouciation "Pik Ass" or "Pick Ass", particulary in war-time military organisations, where people of all German provinces were mixed together. So, I would not make a big deal concerning this spelling.

In my experience, all official German military print-products always had the printing factory mentioned. Here it is the printing company Oldenbourg in Munich, which is not the publisher, but the company which finally prints the product. It makes sence in this case, since it is in Munich as well as the manufacturer of the engine.

The 2000/IV./III. is for a date-term in Germany completely unusual.
Noone, who grew up with the German language would ever use such a "monster", to tell one other a date. If it wasn't imprinted postwar, this must be an internal serial of BMW, RLM or the printing company.

A happy new year and hope this helps,

All the best !
