Those look like eight bolt wheels so you're probably looking at a 3/4 ton rather than a 1/2 ton (100). Flatbeds are more commonly found on 3/4 tons trucks.
The biggest red flag with any of these old trucks is some of the crazy stuff previous owners may have done over the years to keep them running or working on the farm.
The cab floors are always rusty on these trucks, but I would look for rust holes in the frame rails at or near the front mount of the rear springs.
Good luck
