Have they came close; or is anyone working on a list, by model, of the TC models, the Minneapolis models; and the MM models; the list being production numbers of different tractors of these linages? When a later model of MM comes up for sale, if this list were availible, it sure would help in deciding how serious to get in bidding... The exception for Me would be the G U Z models as I have a lot of time around these.. Thank You in advance MLGoodknight SW Oklahoma
