“Spitfire Security Systems” burglar alarm, Kensington and Chelsea • So far this week we’ve had patriotic WWII alarms celebrating Britannia, Churchill, Blitz – and now comes the Battle of Britain, courtesy of Spitfire Security Systems. I first discovered one of these in Westminster in 2002, but – as with my first Blitz alarm – took a useless photo. This is the only one of the same design I have come across since then, again found in a true blue Tory borough, and despite its age in a pristine condition worthy of the Imperial War Museum, which of course houses a real Spitfire. The Spitfire plane was noted for its superb design, but the same can’t be said of this alarm namesake, which looks like a five-minute job knocked out on a word processor, and gains entry a category I’ve dubbed “basic”, reserved for the most simple type-only designs. The fact that the rudimentary logo is set in a centred serif font with a rule underneath elevates it to the superior end of the “basic” category, but basic it is nevertheless. • Spotted: Godfrey Street, Kensington and Chelsea, London, SW3, England, 2010 • Politics: In the Conservative constituency of Chelsea and Fulham
