Hey Brad,
Stephen Lawson has uploaded a photo of 102/17 on the Kitmaker galleries over on Aeroscale (WW1 1/32 Group Build/ F1) that quite clearly shows the curved leading edge.
On the engines, there seem to be a few different variations on the theme of the Oberursel and 110 Hp LeRhone. I have been trying my self to find definitive evidence of exactly which way the valve tappet levers attached.
I have even seen one photo of a LeRhone with the Induction pipes and the Push rods on the FRONT of the engine?

Yes, the Oberursel was a direct copy... (This photo was actually in the section under Oberursel)

...but the LeRhone was thought to be far more reliable.
Cheers,
