Computer, Battenberg Course Indicator MkIII (FLITEC072)
This 12-inch-diameter metal combined flight and sea computer has been mounted on a wooden base and framed for display.
According to collector George Fulford's notes:
Made by Elliott Brothers London #2221. 12 inches, made of metal and Perspex and mounted on a 18 by 18 wooden base for display on the wall. This one is also in my study, and it’s a flashy beauty to look and talk about. Lord Battenberg was a Royal Navy Admiral at the beginning of WW1 with a great naval reputation. Unfortunately, he was also a cousin of Germany’s Kaiser and the public didn’t like the idea of him help run the Royal Navy in wartime with a close relative like that. So he resigned. The rest of the Royal Family also had ties with Kaiser and also Teutonic names and titles – remember Queen Victoria married a German – and so the Royals changed their names to Windsor to get away from the stigma, and as they were way up in the hierarchy they managed to keep their jobs and palaces. The irony is that Prince Phillip, a competent sea navigator, who is married to Queen Elizabeth is the grandson of Admiral Battenberg. Anyway, the computer was designed for ship use but was soon adapted by the Royal Air Force, and I see it referenced quite a lot in their very early air navigation manuals, though I still haven’t got the hang of operating it usefully.
