This is absolutely brilliant. The design and manufacture of Raleigh bicycles in the mid-40s, as told by a designer to a father and son.
The process of manufacture is traced from the beginning; the design on paper and the raw materials. We see what goes to make the steel tubes of the frames, the handle bars, the gear wheels, the pedal cranks, the pedals, the spokes, the wheels and the hubs, until at last the complete bicycle is ready for testing.

Hat tip to Mr. Jolly for sending this my way.
