I only just found this out myself by chance! Sir Alliott Verdon-Roe was well known as the founder of aircraft pioneers AVRO, later famous for the Lancaster of course, and of flying boat manufacturers Saunders-Roe who later became famous for their hovercraft. But which company did he and his son Geoffrey also start, which has helped many of us here out of a problem thanks to its best known product? The clue's in their name...
Cheers,
Andy
