Hello,
Currently on ebay is a photo of Rumpler C.I C.1877/15 at:
https://www.ebay.de/itm/Original-Fot...IAAOSwCFFfxzZZ
This image shows the same machine shown with FFA 17 at post 8 of this thread (no longer viewable) and also here :

However, it does not have the diagonal band of FFA 17 and may possibly be shown here while serving with FA (A) 221.
Regards,
Clint
