Hi, Byron...
This is one of those confusing photos, and I was waiting to see who would bring it to this thread...

. If some sources state that it is 9.Staffel, then why is the propellor spinner white? I know it's a small thing, and I accept it could be a spinner change due to necessity, but the German practice of colouring the propellor spinner in the Staffel colour -
if applicable here - surely rules out 9.Staffel, as that Staffel's I/D colour was yellow.
However, the photo below, from
www.warbirdphotographs.com, does somewhat contradict things, as it quite clearly has yellow spinners...!
I am still as confused as I was at the start of this thread...
Regards...
Paul
