Not a product of the Morris Garages car builders but a Formula 1 racing car with a body made from lightweight magnesium. This car is yet another fascinating piece of auto-racing history from Greg_998 on Flickr. In the late 1960s Honda saved 80kg from the weight of their previous F1 car by giving its body a magnesium shell, instead of an aluminium one.

This author fondly remembers setting fire to strips of magnesium in chemistry lessons, something which is now probably banned under Elf & Safety. Magnesium burns at roughly 3,100°C, making it great for things such as distress flares, sparklers on bonfire night and those things that Boy Scouts start fires with. Tragically these properties make it an incredibly dangerous material to have built a car from if it crashes and catches fire.
