John:

According to my Minneapolis Moline book by Peterson &amp; Beemer, the G940 was an Oliver built product. They were only produced in 1971 and except for the MM Grill and the Energy Yellow paint they were the exact same tractor as the Oliver 1855. The one you are talking about must have been repainted somewhere alomg the way after it left Charles City.

The G940's used Oliver 1855 serial numbers so there is no way of knowing exactly how many were produced. I would like to think that there were a lot more 1855's produced in 1971 that G940's. It should be more rare than an 1855.
