A very interesting clock called 'Compos Mentis'. From the outside it is a very old beautiful oak box that has a handle and some catches, and it dates back to about 1910, made for the medical profession. Lowering the flap on the front reveals the Nixie tubes that the clock tells the time with. The tubes for the seconds are slightly smaller than the hours and minute tubes, to help set them apart. Opened up, the box is an old electrical shock machine. I've kept all the fitted tools and hand grips used to administer the shock with. The casing and all the original mechanism has been restored. One of the original switches on the machine has been rewired to blank the tubes on and off. A really nice conversion, and hopefully will not be the last one of these I'm asked to make.
