Jamo,
Thanks for posting this trip down "memory lane", it caught my eye immediately when I saw the name Peter Endsleigh Castle. As a youngster I had a standing order at a local bookstore for the monthly copy of RAF Flying Review and his work fascinated me monthly. Later, when I joined the RCAF and modelling became only an occasional pleasure, I collected the Aircraft in Profile Series which were lovingly bound into the vinyl Series wire framed covers, and pored over for endless hours.
It's very interesting to note the different depictions of that period and contemporary work, for example DH.2 6011 shown here (which I'm working away at presently) and also a Profile in the Albatros Data File, and the same for MVR's DR.1 152/17. I've always regarded the Data Files as the "Bible" of the genre; I suppose the differences result as more information or technology surfaces.
Great article, and much enjoyed and appreciated!
Cheers,
Lance
