Well, it is identical to the hardback copy I have, same cover, same text
and font, same pink colour and 125 pages. The publisher's name is on
the spine and on the back cover and not on the front.
Mine still has the loan library sheet in the front from the Royal Radar
Establishment Library in Malvern Worcestershire. So I'm sure mine is
genuine. Bought by the RRE on 2-Feb-1968!
I wonder if you have a different book? Could you extract and post, say,
the contents page so I could compare? Or is your copy available for
download anywhere?
