SmartHughes Bros and Hillhead were under the same company , that lorry was an early one , still on 40by8s . The one that went to Hillhead had 1000 by 20s and the manual 12 speed box . The little vent on top of the cab had a mirror for loading , also useful for checking for police cars sneaking up behind .
That has finally answered a puzzle that I wondered about 60 years ago when I saw them as lad. Thank you.
Some of Ballidon quarries Kew Dodges in the fifties had those mirrors as well. Back to that Foden: I assume that was about the same time as the NORDE artic was developed at Darley Dale to do a similar speed then? Those worm and wheel Foden diffs were not really designed for those speeds though, but if hypoid ones had been available it might have been even faster as there was less drag on those!
