The tractor is a Fordson Super Major of about 45 hp flat out - it would have been blue with orange front wheels. Probably cost about £950 new and was built in Basildon.
These days it would have an EEC-specified roll-over protected cab, be fitted with air conditioning, heater and stereo, multiple electronics, have at least 120 hp, cost at least £30 grand and be built by the Fiat/New Holland/Case/IH conglomerate anywhere but in the UK!
That's progress - the UK tractor building industry has gone pretty much the same way as English Electric and the Lightning
But how the f*** did that photo get taken???? There's been no reply on that one
