Olympia Typewriter Model Serial Number Database 06.01.2012 · Model Monica begins: a stripped-down model that began in 1960 and continued until the end of Olympia production in Germany, spanning a number of body styles. The first Monica was similar to the SM2, but without a chrome stripe around the base of the machine, with different, simpler rubber feet, and less liberal use of chrome finishing. The eraser table is also lacking.
