On the same track as this, I have a Massey Ferguson MF35 Utility Tractor. This tractor was purchased by the Army Corp of Engineers (with Brass Tag) and USAF marks on it. Massey Ferguson made these tractors in the fall of 1963 and there was only 167 of them. I am having issues find information on these any where, as well as the finding the meaning of some of the marking. Is there anyone who could help of point me in the right direction. I have talked with the Army Corp of Engineers in Washington for 3 months and got nothing from them, I am a member of the group FENA (Ferguson Enthusiasts of North America, www.fergusonenthusiasts.org) this group has given me the most information about the tractor. I have pictures of my tractor and of one that had been restored. I would like to restore the tractor that I have, however I want to put the marking back on it to honor where it served. I would also like to find out the history of what it did and where it served. Thanks for the help
