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. Unlike the later unitary construction 3TA 350, the 3T possessed a measure of the low-down 'grunt' associated with Triumph's larger vertical twins and as a result is arguably a much more pleasant and charismatic machine to ride.
This 'barn find' Triumph 3T was acquired from the vendor's late father-in-law circa 40 years ago and has been in storage ever since. Last taxed/MoT'd in 1976, and apparently complete, the machine is offered for restoration and sold strictly as viewed. Accompanying documentation consists of an old-style continuation logbook (issued 1968) and an old MoT certificate (expired 1977).
