We have a 1066 that was my father in law's first tractor with a cab.  I'd like to know what year it is.  The serial number is 2610154U008105.  Based on what I'm finding on the internet it would be a 1971.  About the 1004th one made.  Am I correct in that assumption?  I know very little about the old red stuff, I grew up on old Deere stuff!  My wife is interested in finding out when it was made.  Hopefully in the future it will be a candidate for restoration for sentimental reasons only.
