Well, I got a Selene build on a Fordson Super major new performance 1963 a while back. It has a Silvant winch on the back.
Here are some pictures
These are the current sizes of the tyres. I might get bigger wheels at the back.

Nice find, it only needs a clean and it'll look great. The LH rear wheel seems to be missing a rim mounting, I would stick with the sizes you have, as lots of people do fit bigger tyres and then you struggle to find Selene and Roadless Major's with std. wheels. Nice to see an underswept exhaust on a 4WD Major.
