CMP chassis

[David_Hayward (RIP)]

I have been trying to work out where the F-8, C011DF, chassis design came from. I think it is taken as read that the 8-cwt chassis were based on 3/4-ton or 15-cwt commercial chassis but there was no 1940 commercial Forward-Control or COE 101" wheelbase below 1 1/2 tons, though arguably that design formed the basis of the F-15. Apart from cabs, wheels, tyres, etc. was the F-8 downsized in the chassis department from the 15-cwt and above series? Lighter chassis rails perhaps or were they much the same?

I have just found evidence that suggests that the use of a Ford 30-cwt chassis to create a WD 8-cwt 4 x 4 has precedent. In theory therefore the F-8 and its successor the F-8A could well have originally been conceived as using 1 1/2 -ton components after all! Seems like overkill to me but I leave the comments thereon to you experts.
