Hello,
On ebay at :
https://www.ebay.de/itm/Foto-2-Westf...oAAOSwIKZdSxZD
is an image of a french aircraft with a red cross. I believe it may be a Farman F.403 see:
https://d551.skyrock.com/3182932901-FARMAN-403.html
Can anyone assist with the id and either confirm it is a Farman F.403 in the first link, or failing that id the machine shown.
TIA,
Clint
