However I do have a four edition set of " Aircraft Identification friend or foe? "
Revised edition, produced by " The Aeroplane " magazine in Dec 1940 to Jul 1941.It is in a similar format, with photographs and silhouettes.
It includes the Heinkel He 113 " which has shown itself to be faster and much more manoeuvrable than the Me 109, but has been shot down by Hurricanes and Spitfires ".
I think you have hit upon an element of continuity there as the 1949 "Observers " pays tribute to Aeroplane for illustrations and "the outline sketches showing them from three different angles".
The He 113 saga is officially explained, although I have chatted with one BoB pilot who swore he engaged one off Northern England. His is one of a number of accounts. I do wonder sometimes about possible semi-official operational evaluation, but there is no firm evidence.
However:
"Absence of evidence does not necessarily indicate evidence of absence"
