Dan-San,
Firstly I'd like to thank you for a most informative reply.
I have since dug up an article (OTF Vol. 11 #3) on the Dardanelles Fokker Staffel which claims the following type identities for my four Fokkers:
Fokker E.I 36/15, w.n. 286, Ottoman serial F1.
Fokker E.II 93/15 w.n. 346, Ottoman serial F4.
Fokker E.III 96/15. w.n. 349, Ottoman serial F3.
Fokker E.III 108/15 w.n. 361, Ottoman serial F2.
Then there is the elusive E.II serial 23/15 which doesn't seem to be mentioned anywhere except in that Windsock DF and that apparently didn't get an Ottoman AF serial.

That confirms the type identity of 23/15 as an E.II but the OTF article got the type identity of 36/15 wrong.

Does this mean there were E.II machines powered by the 80 Ps U.O? I always thought that one of the main differences between the E.I and E.II was the type of engine installed?

If I recall correctly 98/15 was originally an E.II. There are photos of it both as an E.II and later after it was apparently rebuilt into an E.III in one of the Windsock Datafiles. Another interesting point is that the above mentioned OTF article (which cites a Turkish source) gave the w.n. 346 as corresponding to E.II 93/15. So either they got the serial or the w.n. wrong. This is becoming confusing....

That I can believe, Fokker seems to have worked very much by-the-seat-of-his-pants.
