[GreenKeys] Number of teleprinters built

[Nico de Jong]

>From the numbers I've received until now, we can safely say that in the US 
more then 2.500.000 machines were built alone by Kleinschmidt and Teletype 
(> 1.000.000 resp > 1.500.000)
For the Teletype model 15, Wikipedia tells me that during the 28 year 
production time, around 200.000 were made.

Truly astonishing numbers, I must say
