When writing the blog about wiring colour changes, I recalled the very complicated gas meter arrangements in the Factory of CCT Theatre Lighting in Windsor House, Mitcham. It had previously been the factory for Windsor bathroom fittings who made taps & suchlike, presumably needing a lot of energy for casting, chroming & foundrywork.
Don Hindle, the MD, used to refer to the labyrinth of cupboard plumbing as “three phase gas”.
