Oh gosh, that is tough without seeing the tractor! I have a 99, which is a little later, it was stuck when I bought it, cost $350, I also have a model A, it is sort of stuck, not solid yet, it is pretty much the same, made in 1930, I gave $2,000 for it, but they only made that model in 1930, the 28-44 is a decendant. Whatever both of y'all are happy with is probably a good deal!
Have a great day!!!
