Triumph launched in 1923 and by the late 1920's had the Super Seven, then eight and followed by nine. Then the sportier models of Southern Cross and Scorpion and Gloria where there were 3 chassis types and 6 engine choices culminating in the Dolomite, so the factory was spreading it's fiances thinly. There was an attempt to get into the top echelons of sportscars when Donald Healey moved there and oversaw the 8C Dolomite project, basing the engine and brakes on the already dated 8C 2.3 Alfa.
Postwar the car company was absorbed by the Standard Motor Co. producing the Roadster and 1800 Saloon and by 1953 the TR2 entered mass production, where it was successful in exports which the post war British economy needed. The TR2 evolved into the 3 and 3A. There was also the Triumph Herald. Later Michelotti modernised the look of their sportscars with the TR4 for 1961. Triumph became part of the Leyland empire giving it new impetus ending in the V8 engined Stag. Their smaller Spitfire took on the MG Midgets and Austin-Healey Sprites. Then there was the coupe GT6 and Stag mentioned. And lets not forget the 4 door 16 valve Dolomite Sprint which was also used for competition. The last Triumph left the factory on June 9, 1984.
