Actually it appears that in the photo of Renz, taken in late 1941 or later based on the spange award being worn that he is likely wearing a combined pilot/observer badge.

It was not overly uncommon to have observers later completing their pilot flight training and then being awarded the pilot/observer badge which design wise was identical to the pilots badge with the notable exception that the wreath was gold.

I have a number of document groups where this is the case that the Beobachterschein (observer license) was followed some time later with the individual receiving his flugzeugfuhrerschein (pilot license) at which point the combined badge was issued/awarded.

Cheers
