From what I can see, it looks to be mostly correct as stated. Front wheels are older American style that have been cut off and converted to rubber tire rims. Rears could be the original English wheels cut off and converted to rubber tire rims. This makes the tractor driveable in parades, etc.
Lots of parts and information are available.
I think the $2500 asking price is pretty fair for a pretty decent tractor.
You have to be stuck on Fords to admire it. It gets attention because not many show up. Make sure that the carb isn't an excuse for not showing how well it runs. (or badly) Besides carb, the magneto and governor could need work. It's a hobby. Even after repairs, it won't go up enough to recover your expense.
Remember, you need to be a pretty strong person to crank start them, and with worm drive you can't pull-start them without wrecking something.
