Hello Peter,

Hopefully one of our resident Typenschild experts will answer-up. Meantime, I’ll take a stab at it.

Luftwaffe aircraft engines usually featured a Typenschild (ID tag). These tags were much like to ones found on Luftwaffe aircraft and listed: Gerät-Nr. (Model number); Werknummer (Serial number); and a Manufacturer or Hersteller code (three letter ID maker code). These were riveted or screwed to engines in various places.

In addition—especially later in the war—BMW 801 engines often displayed their six-digit Motornummern roughly hand-painted on one of their cooling fan blades, and/or in larger numerals on the lower oil cooler ring.

I hope this of some help.

Respectfully,

Steve Sheflin
