Hello Ray
Firstly thanks for bringing out a special on the early Zeppelins, I will have that one when it comes out along with the v/1500 you just launched.
The second thing is just a suggestion, how about covering British Airships. For the rigids you have the R23 and R23X types or for the blimps you've got the Parsevals (actually several nations with these), North Sea Class, Coastal class, Coastal Star class and the SS Zeros (the most numerous single type of the war). I know you covered the SS BE.2c in Windsock Worldwide a while ago but the list above should provide several Datafiles surely.
Cheers, Alan.
