RAF Publications!
I have over many years collected a number of RAF Air Publications (AP's) and whilst in some cases have learned some interesting details have also enjoyed them for general reading and reference. The first one I acquired was a war time copy of AP1234 the Navigation manual and later the Flying manuals AP129 Vol 1 & 2. These were later combined with AP1234 to become several volumes of AP3456.
In addition I also have an interesting soft back pamphlet type publication entitled "Instrument Flying" namely AM Pamphlet 208
Anybody discovered any others of interest?
