I have often thought that a "Dual High" could be incorporated into a torque tube - but done "backwards" to offer an overdrive.

By the time you are done, you may as well buy a Mitchell Tranny.

I have observed that the dual high seems most closely associated with the three speed Model A transmission. By the time the four speed was offered, the low end gears were considered low enough so the dual high wasn't required.

Instead by then everyone was buying a Warford for the Model AA - which offered an overdrive.

The special parts to mate the Warford unit to the Model AA were included in the "Green Book" (1947) Including the special mix/match universal joint.
