Hi Euan, I am from the area, I am afraid I do not know of this motor,but I do remember occasionally seeing a BT Landrover in the old PO garage in Cambell St Dunfermline round about the 1980,s(I was a Royal Mail buildings maintenance engineer until last year) It was fitted with a front capstan winch which was used to pull cables through underground ducts. On each front wing was an emergency stop button to be able to stop the engine in a hurry if required.
