Nothing New Under the Sun
Its an old phrase but nothing fascinates me more (apart from ISO containers, bridges and MEXEFLOTES) than modern technology that is assumed to be new yet has been thought of, designed and used by our forebears.
This is just a random example but have a look at this
Standard JAB Mk II had several modifications, including redesigned wings. Only about six of these vehicles were built. The front axle drive casing was cast as an integral unit with the engine sump. The tires were 7.50-10, a special aero tire , modified to have cross-country tread. Also seen here is an amphibious trailer into which the front end of the vehicle was to be placed, for ferrying across rivers. During the first test in a water tank, the outfit sank straight to the bottom. Afterwards, four empty Jerry cans were fixed to the rear corners of the trailer for extra buoyancy.
