Thanks Bertrand,
I've just been on Albin Denis looking at his Esc 107 page. He has photos of Sopwith 1B1 No.185 in German hands. Different photos to this one I think (alarming how your memories goes - it was only about 10 mins ago).
One ot two of the other machines have been photographed before, though I must say the photos in the album are nicer than the previous ones i've seen and the Nieuport B3578 of 29 Squadron was new to me, no doubt if I do an internet search that will turn up too.
Also I'm wondering if the album is definitely FA (A) 287, note the Fliegerabteilung 102 marking on the car.
Regards,
Clint
