Triumph re-entered the 350 class in 1957 with the introduction of the 'Twenty One', its arrival ushering in Triumph's unitary construction era. The model took its name from the engine's approximate cubic capacity in inches. Readily distinguishable by its 'Shell Blue' metallic finish and 'bathtub' rear enclosure - a feature later applied to Triumph's larger models - the newcomer was renamed '3TA' in September 1958. With just 18.5bhp on tap, Triumph's smallest twin lacked the urgent acceleration of its larger brethren but nevertheless was a capable tourer good for around 80mph while delivering excellent fuel economy. "One of the swiftest standard British-made 350cc roadsters tested by Motor Cycling, the Triumph Twenty One combines an untiring zest for high-speed cruising with safe handling and a remarkably economical fuel consumption," reported the popular UK magazine. Nothing is known of the history of this particular example other than the fact that it was last licensed 1958. Without reserve
