Like them all, but love the "B"s.

Look at the waterpump sheave (pulley). It has slots and screws which allows the effective diameter of the pulley to be adjusted. This was the only adjustment on the early tractors without a generator but comes in handy sometimes with the generator equipped tractors as well when you need just that little extra adjustment.
