Hi Nick,
Thanks for the reply. I've has a response on the Great War Forum
https://www.greatwarforum.org/topic/...at-netheravon/
making the same suggestion as yourself. So possibly that is the case.
However, I 've also received aa suggestion that the aircraft may be 7034 and that there is a speck on the camera or a distortion caused by the wing. Again possibly so.
I fear that it may actually take another photo of the aircraft to settle this. Alas while the seller says that he has a couple more photos of the machine,neither show the serial.
Regards,
Clint
