Looking more closely, now I see it is a copy of 80's model Shibaura Fords. So, not being well versed on Chinese tractor history, I don't know. It is an interesting specimen. Does it run well?
Was the seller's name Jonathon Cash?CE24C which would indicate that it is a 1970 May 24 Afternoon shift tractor - Fine. However it is only 3 cylinder not 4 and only has one fuel filter not 2. The engine code is C9 NN 6015 A = means that the engine block is a 1969. Also interesting the gearbox shows that it is C5 NN 7006 which means that it is from a 1965.
