From the 1970s is this Imperial 2002, and very of it's time it is too. Its in a rather nice cream with a space age font for the model name (very 1970s!) The typewriter is in good condition and rather clean too unlike some of the others in the collection.
Imperial was a typewriter manufacturer based in Leicester. However, in 1966 it was bought by Litton Industries and it's products became based on the Royal Typewriter Company's range. Production ceased in the UK in 1975. The 2002 was built in Portugal in the late 1970s and by now the "Imperial" brand had little in it which was British. This doesn't stop my 2002 being a very fine typewriter.
