Hi Steve. I just remembered something. There's a fairly good article on F.A. 300 in the Middle East entitled "Wings over the Sinai and Palestine" in "Over the Front", Vol. 13, No. 1, Spring 1998. This is the journal of the League of WWI Aviation Historians, an offshoot of the Cross & Cockade Society in the U.S. The article has lots of photos and good reference notes and sources. It was written by a couple of German scholars (in Englsh!) and is about 60 pages long. If you cannot easily locate a copy (you can buy back issues through the website), I would be happy to photocopy the article and e-mail it to you.
Regards,
Bob
