Chronometrics - and the dashing of Imperial hopes
Chronometrics are based on French Jaeger (therefore pronounced "jejere", not "jager" as I pronounced it for years) speedometers, using French Jaeger patents. Smith took Jaeger over / bought a controlling interest, whatever, and retained the tradename for a while. Upmarket cars had Jaeger speedos, the hoi polloi, us, or at least me, had Smiths. They were in fact the same. However, many of the threads on Smith Chronometrics are from a now obselete French metric thread system, with no modern equivalent.
I'm reluctant to explode the amazement this effortless display of arcane knowledge may (bloody well ought to...) generate. But any VMCC member who read the same six articles on Smith's chronometrics that I read (and scanned, and re-read) could tell you the same.
Where credit IS due, is that several months on I REMEMBERED.
Got to go. Lost the car keys again...
