Hello Nick,
Thanks for the info I've ordered both volumes of the datafile specials.
Additionally currently on ebay a photo of a line up of Nieuports including N1590 and N1420? currently at:

captioned as Nieuport 17, but is that a 16 I see low down on the rudder of the foremost machine?
Regards,
Clint
