The Morkrum Company Model GPE Perforator was designed about 1913 and
continued to be produced for the next 50 years, a corporate record. It was magnet driven,
and was very fast, being a "work horse" during two World Wars and the intervening
Expansion and Depression eras.
GPE was for Green Code Perforator, but it was also called the "Iron-Horse" Perforator.
The Green Code name came about for Western Union equipment, which used an olive-drab
The GPE was produced from 1913 to 1925 under the Morkrum Company, from 1925 to 1929 under Morkrum-Kleinschmidt, and from 1929 to 1963 under Teletype Corp. However, the GPE may have carried a "Teletype" nameplate and the scroll symbol as early as 1921.
(need more poop here)....
Standard Model: GPE
|This later-model GPE used the cushioned green keyboard, and had a sound-dampened cover.|
|This guy is in great condition.|
|The machine has no motor -- solenoid magnets power the tape punching.|
|More mechanics than circuitry. This would be the case for Teletype machines until the Model 32, which included a fair bit of electronics.|
|These GPE units look to be an earlier production -- or are they just dirtier?|
|This one looks much earlier -- the keycaps are different, and there is no large button on the right. The logo plate likely is Morkrum Company or Morkrun-Kleinschmidt.|
