Oh yeah, the classic sci-fi TV puppet show? Er no, I was thinking about the classic 1950s motorcycle, the Triumph Thunderbird.
Never heard of it. Well, anyone who's into motorbikes has. Its sleek, cast-iron frame was considered lighter than its European and American counterparts, and in its day it became a byword for cool on the road when Marlon Brando rode one in the 1953 film The Wild One, one of the first movies dedicated to youthful rebelliousness.
When? 1949 saw the first Thunderbird roll off the production line.
Who? Edward Turner of Triumph Motorcycles, one of Britain's best-known and surviving manufacturers.
Er ... who? Turner, Triumph's general manager and chief designer from 1936, worked with the company's engineering designer of the time, Jack Wickes, to create the T-bird, as it was often known.
What was so special about the bike, then? It delivered more power and acceleration than most other motorcycles of its size - about 34 horsepower - thanks to its vertically mounted 650cc twin engine.
