1968. My old AEC Mercury tanker parked up at Hey Farm. The tank was a Darham, stainless steel, 1865 gallon.
In 1976 it was being used at the Dairy as an outside holding tank for washing water.
Twenty years later it was still being useful at Bail Farm as a reservoir for the detergent used to flush the milk lines in the parlour.
I always had a soft spot for this tank, beautifully made and it always looked smart. Very easy to keep clean. I don't know what it cost new when J&E Hall at Lancaster bought it but it was a good investment!
