Hi Hans,
I found this site on the Venturas,
http://ns33.hosteur.com/%7Eheinzkno/.../Victory_2.htm
In the article, it speculates that one of the Venturas could have been Knoke's claim.
There is also this site but not sure how accurate it is,
http://www.dehavilland.ukf.net/_DH98%20prodn%20list.txt
though it looks very comprehensive. Any idea who did the work?
Not to go OT but how accurate is Knoke's book,
I flew for the Fuhrer.
