And my 1976 American Ford tractor has a British Lucas
generator with two bearings.  One bearing is metric and
the other bearing (the two ends of the same shaft) is
English-American-inches.  Fortunately ALL of the
cylinders are diesel.  I'd REALLY be upset if some
cylinders were diesel and some were gasoline/petrol.
