The correct designations of the designs of Frits Koolhoven
('Frederick Koolhoven') is one of the mysteries of aviation history. All great historians have tried to crack this nut
Much study has been made in the following Dutch language books on the designs of Koolhoven:
(1) Dik Top. Frits Koolhoven en zijn vliegtuigproduktie. Repro-Holland, 1996.
(2) Theo Wesselink, Thijs Postma. Koolhoven - Nederlands vliegtuigbouwer in de schaduw van Fokker. Romen, Haarlem. 1981. ISBN 9022838900
Much confusion is the result of Koolhoven himself, who made sometime in the thirties a list (from his memory) of all his designs untill then. To say the least his recollection was unrealiable from the early times up to the F.K. 22 in 1918. Dik Top in his book gives a double list linking the Koolhoven recollection to the possible correct historical designations (
, that's what it says there).
About this Triplane
in this double list is says [Koolhoven recollection list]:
Armstrong Whitworth Triplane (first version of this triplane)
Armstrong Whitworth Triplane (second version - the one of this Challenge - 7836
The possible correct historical designation of these machines is given as:
Armstrong Whitworth Triplane (first version of the triplane)
Armstrong Whitworth Triplane (second version - 7836
designation of this one-only machine is than Armstrong Whitworth F.K.12B [Frederick Koohoven list - 1930's] or Armstrong Whitworth F.K.6 [the possible historical correct designation].
For once you see again theat Internet is good medium, but just as with books, when new information / evidence comes up it must be incorporated in the information that is alreadfy there,
An example of incorporating evidence is the RAF Museum Thesaurus who have chosen here
for the designations F.K.5 and F.K.6 for the two versions of the Armstrong Whitworth triplane. But
.... they still have left in the F.K.12 [Frederick Koolhoven list]
But, I rest my case.
