[Jim Haynes]

I remember seeing something from around 1960 which said that
about 150,000 Model 15 machines had been made.  Or maybe it was
300,000.

Teletype News recorded in Jul-Aug 1960 production of the 100,000th
Model 28 typing unit.  The first units were produced in 1950; and
the armed forces had first priority on all production until the
end of the Korean war in 1953.
