Its early 1970's. If you can supply the date code typically found along with the Ser. No. & Model No, which you've supplied it can be decoded. It will be number,letter,number,number,letter. E.G., 1B12B = 1971, February, 12th day, shift (all were built on the day shift at Highland Park & Romeo). The part numbers indicate: C9NN = 1969 basic design level & design change E = 5th change to the basic part 9425 (which is fuel system part, engine = 6000 series of part numbers). The trans case is a C7 = 1967 basic design. The NN = Tractor Operations.
