I think the book was first published in England in 1962. I believe I bought mine in 1968. It is small but includes almost all AC used in WW2 and seems, based on later publications, to be pretty accurate. Very handy to use.
I was away on vacation when you posted this and got home today to see if there way anyother book I could suggest. That was my first serious book on WW2 Aviation I got oh so many years ago and even today is one of the first books I will open
