Mercedes-Euklid (1905)

Martin (US), pages 156 - 163

Martin (Dtsch), pages 165 - 174 & 433 - 435

 

"Designer: Christel Hamann of Berlin. Manufacturer: Mercedes Office Machine Works of  Berlin. The principle upon which all Euklid models have been based differs entirely from the calculating machine systems so far described. The actuating mechanism consists of ten parallel racks that are proportionally displaced by a lever connected to the racks."

In the 50ties the following models were still build in the Mercedes factory: 21, 29, 37, 37SM, 38, 38SM with the prefix of "R", i.e. R29, etc. The green/black color was replaced by gray and the name changed from Mercedes Euklid to just Mercedes.

From ca. 1963 the machines were sold under the name Cellatron.
