Talking of all things small....I remember back in the 1950s, there was a steel tube manufacturing company named 'Talbot Stead', located in the Walsall area of what is now the West Midlands.
A firm in America also making steel tubes, sent Talbot Stead a sample of the their smallest tube that could be made.
Talbot Stead produced a tube....fitted it 'inside' the tube made in America....and sent it back.... Mick
