That Westinghouse has seen better days. Is that smoke on the inside of the globe?
I've worked in that industry since 1980, for companies that make electronic watthour meters. I've lost a good deal of hair trying to explain how a computerized meter works to a guy who cut his teeth on mechanical registers. (And lots of them have reminded me that they could still read their old mechanical meters with a flashlight, while mine needs to be powered up for the display to work.)
For a short time in the 80s my company (Scientific Columbus) made a digital demand register for mounting in a mechanical meter, but we never sold very many of them. GE pretty well had that market tied up.
