 John E. Molle, a jeweler and watchmaker in Sturgeon Bay, Wisconsin, U.S.A. filed his first design in patent 1903, and struggled to finance manufacure until finally successfully bringing his machine to the market in 1918. By then his design, though interesting, was dated and too unusual to succeed greatly in a marketplace now dominated by smaller, lighter portables and 4-bank machines of conventional design, and the venture failed in 1922.
"Molle" is pronounced as "Mollie".
  • On the earliest machines, the words "OSHKOSH, WISCONSON" are printed on the base of the machine below the company's name. "Molle" is printed on the paper table. Very, very early machines have nickle-plated sides.
  • Subsequently, the words "OSHKOSH, WIS., U.S. of A." are printed on the base of the machine. Also, an emblem appears on the paper table adjacent "Molle". The emblem displays a "T" superimposed upon an "M," creating the "MT" logo which presumably stands for "Molle Typewriter." These machines are rare.
  • After a brief run the emblem disappears. The words "OSHKOSH, WIS., U.S. of A." remain.
  • The Liberty maintains a similar design, but featuring the words "CHICAGO, ILLINOIS, U.S. of A" on the base and "Liberty" on the paper table. Same paint scheme and lettering style. Also marked No. 3.
