Hello,
Currently on ebay are a number of photos of Spad S.13 at:

The seller suspects that the aircraft are 95 Aero Squadron, but the text on the rear of the photos is french. One aircraft appears to have the personal name Odette below the cockpit. OK could be a USA pilot with a french girlfriend or then again not.
Regards,
Clint
