One of the earliest British production diesels, designed by Henri Baigent and manufactured in relatively small numbers during 1947 by a company in Bournemouth, England called Bijou Mechanical Productions (Bournemouth) Ltd. This 3.5 cc diesel was the first twin ball-race design to appear in Britain - indeed, one of the first such diesels anywhere. It was extremely well made and a fine runner, but very heavy for its displacement. A detailed article about this engine may be found on the "Model Engine News" (MEN) web-site.
