Hi Bruce,
Your wheels are 20x6 with an inner tube and locking ring, 10 lug on a 7.25" bolt circle, and are "hub piloted" on a 4.75" hub. Fronts and rears are identical, with a cover plate over the front wheels that blocks five of the lugs while adding a little strength, so your showing only 5 lugs on the front even though it's a 10 lug hole wheel. I don't remember the offset.
Be careful buying new wheels, the hub size changed in 1954, to 5.25", and those wheels won't be safe on your truck (no centering from the hub). The ultimate authority here is Grigg, and his "Wheels and tires what to do" will tell you most of what you need to know, even though it's aimed at later (AD) trucks.
My 1935 1.5T had a 207, and I think yours does too if it's original. If the engine is not repairable, consider upgrading to a 216 or 235. I have a 216. It looks like a 207, but it's a MUCH better engine if you plan to drive your truck at all. It's also a lot easier to find one. Mine has a later (1949) bellhousing, mated to the original transmission (double clutching is fun!).
I think your brakes are hydraulic but not power assist. If you keep it down at it's design speed (mine's happy at 45 mph), and don't put a load in the back, the brakes are fine. I've had a half a ton in the back of mine, and that DID increase the stopping distance to an uncomfortable amount. I have mechanical brakes, but there's no difference in the stopping power between well adjusted mechanicals and unassisted hydraulics if your right leg is in good shape.
