Here's something that might while away a few minutes whilst practising your social distancing skills:
http://www.douglas-self.com/MUSEUM/museum.htmPetrolheads might wish to start with the "N-wheeled cars" pages, with perhaps an excursion into gyrocars. The "Gearwheels from hell" page right down at the bottom seems guaranteed to scramble the brain of anyone mechanically-minded. But for sheer undiluted "What were they thinking ?" I would recommend the page on "Combat Cutlery".
Anyone got any other favourite sites that might enliven our outlooks in these challenging times ?
