Ralph Broad was the founder of Broadspeed in the 1950's at 101 Stratford Road, Birmingham. Although Broadspeed are probably best known for the Ford Anglia and Escort but they were racing Mini's until 1965. In the book shown below which is a compilation of articles on Broadspped cars, there is a picture of a Morris Minor so I can only assume that they worked on them as well, and they did produce items for the early sprites and midgets. If anyone has a copy of the article or can confirm this it would be appreciated.
