I would be interested to see how well that book compares to these ones which I have:
A very different animal, arranged alphabetically by aircraft manufacturer and then chronologically
by type in each manufacturer chapter and is not limited to gun armament and related equipment;
bombs, bomb-carriers, bomb-loading and circuit diagrams, torpedoes and mounts etc. are also included.
The book was published in 1971, and stylistically is very much in line with King's other Putnam volumes,
the writing style is 'old school journalist' chatty, King worked for
Flight for years and had personal
'ride along' experience with various inter-war types, including firing the guns, so many personal observations
and anecdotes are included. Kinda stuffy but jolly at the same time, if that makes sense.
Much less Col. Blimp than some other Putnam authors of the period.
It was supposed to be the first of a pair of volumes, Vol.1 listing the aircraft types and how they
were equipped, Vol. 2 detailing the equipment. Unfortunately Vol.2 never appeared, so a few bits
of tech info that were included in Vol.1 as teasers with the promise of the full story to come remain
as tantalizing hints.
That said the book is really quite good and includes drawings and photos of prototype/one-off
mounts/installations that I've not seen anywhere else. I will be scanning and posting more of
these, along with other 'standard' stuff that is of interest.
