CHOOSE YOUR ‘SIDESCREEN’ TRIUMPH TR

Produced after Standard-triumph failed to buy Morgan, the 20 TS prototype was unveiled at the 1952 Earls Court Motor Show.

Much revised by former BRM man Ken Richardson, it reappeared the following March in Geneva as the Triumph TR2 with a tuned version of the Standard Vanguard’s 1991cc engine that produced 90bhp.

Minor tweaks and larger SU carburettors gave 1955’s TR3 an extra 5bhp. It’s at-a-glance distinguishable by the flush rather than recessed front grille. A year later a ‘high-port’ cylinder head lifts power to 100bhp and front disc brakes are fitted.

Triumph never called it that or badged it as such, but 1957 brought the unofficial TR3A with its full-width grille and exterior door handles. From 1959 a 2138cc engine became optional.

TR3A production ran until 1962, after which a further 3331 TR3BS – the last of the sidescreen TRS – were built, with TR4 engines for the US.
