Hi Stig,
I believe that the Farman in link No.1 is a F.45 as is this:

Looking at Kees Kort's site once again the F.36 looks quite distinctive though the tailplane is not unlike that on the F.45:

The Spad A.2 S.31 of N.73 can still be seen on the Spad thread of this board. I note the seller is the same in both cases.

Clint
