Background
What is very likely deemed too subtle to warrant a separate model designation these days was big news back in the late 1950s. By 1956 the TR3 had introduced disc brakes as standard, making it the first series production model to make these superior stoppers standard fit. Together with a spunkier 100bhp version of the 1991cc overhead valve, four-cylinder engine; the TR3 raised the bar. Leaving the TR3A to simply subtly amend the formula, rather than revolutionise what was already an extremely popular British two-seater.
When launched in 1958 the TR3A added to the TR3 recipe a full-width front grille and such ‘luxuries’ as exterior door handles and a lockable version of the same for the boot lid. The 3A also came with a properly provisioned tool kit as standard (it had been optional on the TR3). The formula worked well as Triumph shifted a very healthy 58,000 TR3As, making it the third best-selling model in the TR range (behind the later TR6 and TR7).
