Monroe Newspaper and Magazine Advertisements


There are many online archives of newspapers and magazines, such as archive.org. On this page I will show various advertisements by Monroe that I have found in such online archives. If you find any others in the archives of your own country, then please let me know at mechcalc a t jaapsch d o t net.

Advertisements

Model D

The oldest advertisement I found is from October 1914 for the model D. These ads depict a machine with pins on the front of its carriage along its whole length. This was changed in 1915 in the last models D and the model E, but the ads showing this continued for some time after that.

Models E and F

Model E and F (and the last model D machines) have a wavy comb-shaped piece between the keyboard and the carriage which is used to align the carriage exactly, and a row of holes on the left end of the carriage and a hook which uses them to lock the carriage down. The first appearance I found of this in an ad is in March 1916, even though the model E came out the year before.

Model G

From February 1919 onwards the ads show the model G calculator. Instead of a row of holes it has a rail on the front-left of the carriage onto which a hook grabs to keep the carriage in place during a calculation. The model G was likely introduced in 1918, and the ads were not either updated or the earliest model G calculators did not yet have that rail.

Model K

The model K is easily recognised by the rounded case. I have mostly found ads from 1923; very few early ones from 1921 or 1922, and also few later ones. Given the popularity of this model I expected to find more.

Model L

The model L is much smaller than the model K and has cylindrical buttons instead of flat button tops on metal stems. From 1934 onwards the Monroe-Gardner adding-listing machine was also advertised, as well as bookkeeping machine versions of it.
