There has been great interest in the recent British M-H 745 wheelbase discussion so thought I would bring this M-H 744 thread back to life, whilst looking through my Massey Harris "Growth" magazines recently for the one which John's Grandfather is pictured, I came across this article which some of you may find interesting.
Here in England we see several M-H advertising pictures of the M-H 744 fiited with the Roadless DG4 Halftrack conversion, so far I have never located a surviving example in preservation, we see many of the Fordson E27N Major tractors surviving with this conversion.
Attached is the "News From The Dealers" page and details the 744D demonstration held on the Estate of Lord Walpole at Wolverton Park, Norfolk, reading the page it sounds like the M-H Roadless Halftrack was so well recieved it stayed on the farm after the demo and never returned to the dealer who was Messrs Randalls of North Walsham.
You can see it in the top and centre photograph, I wonder where it went to after it finished it's working life? Alan this is not far from you, maybe you could do some research? you never know it could still be lurking in the back of the barn.
