The Munson typewriter was invented by Samuel John Siefried. This No.3 model was covered by patents issued on September 17, 1899, February 10, 1891 and May 3, 1892. The patents were assigned to The Munson Typewriter Company of Chicago, Illinois. I'm interested in the Munson No.3 model as well as the No.1, No.2 and Pre-Production models.
