Andrew,
It is indeed a Fordson WOT6, a later one than Mike Kelly showed in his thread a few days ago, as it has the roof hatch and removable top half of cab for shipping, also different cab vents on front. Date of build would be about late 43 to 45.
I was going to ask if the dynamo was any good, because I need one for a WOT6, but it would cost an arm and a leg to get it home

so dont worry
