The idea[]
The production of a cheep and efficient early era 3(?) transistor microchip for basic electrical functions.
Manufacturing[]
The then standard silicon\germanium etching process.
Casing[]
N/A, but almost certainly a painted epoxy/glass filled metal can with 3 metal legs for it's leads.

It was meant to replace transistors like the American 2N34 PNP Germanium Alloy Junction Transistor, so the circuit would have 1, not 3 cans on it! It was one of UK's first moves in to the modern electrical business and it was seen as a national icon at the time.
Like all ICs, it is made to a JEDEC standard and ID numbering code after 1953.
