started with a copy of Lipsia 11, which was soon replaced with own developments. In 1959 production of calculation machines was stopped and replaced with the distribution of Schubert machines under the Rokli trade name (this machines carry a suffix "S" in the model description).
Adding machines were produced from 1953 up to 1975.

"In 1874, Willgodt Theophil Odhner from Karlstad, Sweden, designed his first arithmometer, or hand-cranked calculating machine. After Odhner's original patent had expired, various manufacturers started production of calculators following Odhner's successful design.
One of them was the Multo, manufactured by a subsidiary company of Addo, which later was to merge with the Facit-Odhner concern. Multos were built between about 1949 and 1966, although the Multo name was used on some models of the Odhner as late as 1969.
Unlike its Swedish competitors, the Multo was a 'single-handed' machine. However cleverly constructed it is a sensitive machine particularly prone to sticking and gumming-up - making a workable Multo something of a rarity.
The Multo pinwheel calculator was also sold under the Dixi brand name. There also was a "badge-engineered" Multo which otherwise is identical to the Bernadotte-cased Odhner."
