This company made Unitrol and Duotrol Outboard Controls as well as the Unitrol Steerer steering wheels. This company offered the Duotrol outboard motor control as early as 1948, well before outboard motor manufacturers offered proprietary controls. The "Unitrol Accelerator" single-lever control allowed operators to shift and adjust throttle in one smooth motion. The Unitrol Steerer was a rack and gear single-cable steering system.
