@signed8bit nice shots!
The Triumph name originated on bicycles in the 1880s. Motorcycles were added in 1902. The first car appeared in 1923. The TR series came from the desire to make a simple sports car similar to the MG TD and Morgan Plus Four, but with more up-to-date styling. The “TR1” was shown at the 1952 Earls Court Show. Here is a time-line of the production of triumphs:
TR2 was produced from 1953-55 with 8,628 being built.
TR3 was produced from 1955-57 with 13,377 being built.
TR3a was produced from 1957-61 with 58,236 being built.
TR3b was produced in 1962 with 3,331 being built.
TR4 was produced from 1961-65 with 40,253 being built.
TR4a was produced from 1965-67 with 28,465 being built.
TR5 was produced from 1967-68 with 2,947 being built.
TR250 (the TR5 for the N. Amer. market) from 1967-68 with 8,494 being built.
TR6 was produced from 1968-76 with 94,619 being built.
TR7 was produced from 1974-81 with 112,368 being built.
The TR7 was a controversial car; it introduced us to the wedge-shaped body seen in the TR8. The TR8 was produced for export only, although 18 right hand drive were built for the British market as a coupe or convertible, convertibles being more common. This is the last model Triumph produced.
