Hello,
Currently on ebay there is a photo of a Nieuport with 7072 on the tailplane at:
https://www.ebay.it/itm/265400495968...AAAOSwVsFhjLZP
TBH, I'm not sure what to make of this photo - either a Nieuport 16 or Nieuport 21 seem possibilities identificationwise,with the headrest and partially exposed engine cylinders,but I 've no other Nieuport serials in the 70** range. Any thoughts ?
Regards,
Clint
