Triumph's first 350cc vertical twin had been built for military purposes in wartime and would form the basis for a civilian version when hostilities ceased. The basic engine design followed that laid down pre-war by Edward Turner for the trend-setting Speed Twin but featured rocker boxes incorporated into the cylinder head casting and a built-up crankshaft with one piece connecting rods like the military 3TW. The running gear was essentially that of the Speed Twin and featured Triumph's new telescopic front fork. Lower geared than its 500cc sibling, the 3T was nevertheless capable of reaching 75mph and could return around 80mpg. Dismantled many years ago, since when it has been kept in dry storage, this incomplete 3T is offered for restoration and sold strictly as viewed. Accompanying documentation consists of an old-style continuation logbook and an old-style V5. No reserve.
