And what was wrong with what they taught in the 1930s?!
I have a copy of "Teach Yourself Flying" by Tangye & MacBeath, the 1950s reprint of the 1938 book, and also the AMAC Manual of Flying and Ground Training, (1950s/60s I think), newer, but more comprehensive that the earlier book.
Both are readily available from internet book shops for very little, as little as it would cost us to post them back and for to each other possibly!
PM me if you'd like to peruse
