The Morkrum Company Model 11 Typewheel Tape Printer, at about 45 words-per-minute,
was a bit faster the Morkrum Printing Telegraph Blue/Green-Code printers, and
was somewhat modeled after the European Baudot Telegraph System printer.
The Model 11 was a Tape Printer which used gummed paper tape (that could be pasted onto
a telegram blank). Various types of moisteners were used, each having a container
of water and a felt wick.

One feature first developed for the Model 11 was that of "cushioned" keytops,
which had small springs inside them. The tops were also of soft material, and the
combination had a good "feel" according to the typists using the keyboard.
This feature was carried over to many later Models during the succeeding years,
until replaced by cheaper molded plastic.

Another new feature was the motor driven
"cam-and-contacts" type of sending distributor which took the place of the
"brushes-and-faceplate" type. This too was carried over to many succeeding Models.
The Governor began to look like later versions, but the control
was still on the outside, with an adjusting screw giving precise settings.
White dots on the periphery of the Governor were now used in conjunction
with vibrating tuning forks to set the Motor speed.
The Governor had heavy weights within it, their positions during
rotation being transferred to a plunger on the shaft axis for working the
external contact.

M11 printers were produced from 1921 to 1925 under the Morkrum Company, and from
1925 to 1927 under the Morkrum-Kleinschmidt Company, but were all branded "Teletype."
The scroll symbol was also introduced for the Model 11 machine.
