Years ago, there was one of these in a London Gents Outfitters (Horne
Bros, Tottenham Court Road) that had been surreptitiously calibrated for
the purpose testing Varios.

For some reason I cannot imaging you ever going near a Gents Outfitters
- at least not to buy clothes! Did they ever work out what their lift
was being used for? And did it have a lift operator?
