I believe Mlauk has you pointed in the right direction.
As the link shows, Long marketed tractors from UTB. Long had some type of agreement in the 80's with Ford, but that didn't seem to last long. (pun not intended) Ford partner'd up with New Holland after that, then Fiat bought New Holland and the Ford name went away.
Escort limited, out of India which was making the 3000 & 4000 series Fords back in the 70's, bought the financially troubled LongAgribuisness to market its own tractors here under the Farmtrac name. The larger series Farmtracs are manufactured at the Faribad, India plant, and the smaller CUT's are built by LS in South Korea. (I think I got all that right)
Anyways, you might want to check the availability of parts & service prior to the purchase.
