£3.36?! for 338 pages?! A steal!
My experience is pretty much limited to 263 Sqn, but the appendices were mostly combat reports or summaries of operations in a variety of formats. Most were typed or carbon copies of telex messages, but some were hand-written or contained diagrams of targets and lines of attack. Length varies from a couple of lines through to 3-4 pages.
There were also some sundries; movement orders, nominal rolls of pilots, occasionally write-ups of training or ‘unusual’ duties.
HTH,
