OK, but if you say that the MF based ones had only MFT on them because Moffet had sold the tractor business, how come the later Ford ones have Moffet written all over them? In fact, what I think happened was, the idea was developed by a farmer and taken on by an engineering firm in Co.Louth. This company then sold out at least the tractor enterprise to Moffet, who changed the skid unit to a Ford (much better I think!)
There are two reasons behind my theory:
1: A department guy who came to our farm last year told my dad and brother that his uncle came up with the original idea, and based it on an old Massey. We didnt get any more details
2: I had a brochure for the MF based ones not so long ago, and reading through it I noticed that it made no mention of Mofffet, and showed a photo of the plant where they were made, with an address in Louth.
I hope that this brief potted history helps
