German Ace(?) Waldhausen

Do any of you have any information on this pilot? Ideally, I need a photograph, and to determine if he was shot down by Mick Mannock.

I have very little to work with, only an account by a No. 8 squadron pilot taking about this incident.

Any dates and details are most welcome. Waldhausen did survive the war. I am just frightfully lacking on any German sources in my growing library.

Cheers ya'll,
Scarlett
