I've been wondering how many Avometers were built, and how many of them remain operational. For example, Land Rover proudly quote a statistic that
"75% of all Land Rovers built since 1955 are still on the road" and it would be nice to know the same statistic for Avometers!
Presumably PMM has pieced together some production figures?
As a first guess, between the 1920s and 1990s we must be talking about several million units, with perhaps 30% of them still going. It sometimes feels like most of them are now in preservation at the hands of Forum members, but judging by the condition of some that I've rescued, there must have been a fairly high attrition rate once they got into the hands of electricians and Services personnel
not to mention the number that were skipped when digital took over.
