yep. 5 speed spicer tranny. super heavy duty type of gizmo. gear number 5 was NOT overdrive, but rather direct, however, the gear set is available to make 5th gear overdrive.
big ol' heavy duty cast iron mamma-jamma. maybe a big ol' heavy duty lipe clutch plate an pressure plate in front of it.
the kind of thing you would find on a log skidder.......
