Thanks for sharing Steve! The census number can only be C4847497, with would mean that this is a WD/CO/B with frame number 14497. This bike was despatched from the factory on November 2nd 1942, destination "War Office - South Merstham". Unfortunately it is currently not in my WD/CO Register.
For as far as I could find out, most WD/CO(/B)s were used either by the Home Guard or for training purposes.
