MULDIVO MENTOR MECHANICAL CALCULATOR, 1960's

An Odhner-type rotary pin-wheel machine.

This machine is fitted with a very useful back-transfer mechanism actuated by the small red lever at top right. This transfers the number in the result register back up to the setting register so that it can be used in further calculations.

Muldivo were the British importers and distributors. The machines were made by the famous weapon manufacture Carl Walther GMBH

Donated by Ken Thompson
