I'll let you know Jim, and yes Andy, from the sample pages I looked at, I think it'll be a great reference, especially for BoB stuff. (it's already clarified something for one of my museum projects!).
OK, at £25 for a soft back (A4 size), it's a tad pricey, but considering the work involved in research, cataloging, and the photos, many multiple views, I think it deserves the price tag - and the introductory offer knocks off £5, so only paying £20.
This is Volume One, from 1939 to the height of the BoB, so i'm guessing there'll be another two or three volumes yet to come.
I'll post a review of sorts, when I get my copy.
