ERF I worked for Distillers at Pollard Street Manchester for a short time carting Distillers CO2 on contract with Smith of Eccles.
Chris I had also seen these sort of tankers at was Shell Carrington Manchester but never got close enough to see one discharge. Guessing but would this tank have foot wheel valves on the top or similar to a spirit tank. Notice 4 pots of 1100 gallons and would that be close to 18 to payload?.
