Thanks Nick
Yes I know some of the basics, but what does one do when the cowling is not visible?
How 'bout the model 24bis and the trainer versions in the 80 range?
No I still don't like designs with such subtle differences.
Also thanks for the ID of the aircraft we are looking at.
Somewhere I think I have seen this photo before, but it would take ages to find it (if I really do have it.....)
Good to have a couple of Aces around, when Clint is working overtime to find interesting WW I photos.
Everyone's efforts are highly appreciated by me!!
Cheers
Stig
PS: Since you identified the third aircraft as a model 16 (headrest) it cannot be N1116 which you say was a model 11, even if this one also carries a 'R'.
