The Bulldog was a derivative of the earlier Beagle Pup, although I don't have a Pup manual to compare. There are definitely totally different manuals for the military and civilian aircraft however, as I have both. The RAF manual has a completely different structure (and included a comprehensive, but differently constructed "emergency handling" section).. I assume, but don't know, that the CAA Bulldog manual was derived from the Beagle Pup manual. The RAF manual clearly uses exactly the same structure as all other aircrew manuals of the period.
