What tanks are these?

[david moore]

One puzzle Adrian. These vehicles are headed south - towards Southampton presumably - and then on to France? So, if they arrived like this from the USA - how come they got to north Wiltshire en route? Maybe delivered to Liverpool or even Avonmouth - too dangerous to ship direct to Southampton perhaps - U-Boats and all? Then a long cross-country drive behind Diamond T's ? Ferocious use of gas - or diesel? Why not take the waterproofing stuff off on arrival to save some weight - or maybe want to keep it on for the cross-channel piece?
Note how one diamond T has uncoupled from it's trailer to double-head on the steepest bit - 10% grade there. Leaving a loaded trailer on a steep hill? Wow!
