Publicity for the Appoulot sliderule LOGZ; the item in the collection is mode 3 with a 20cm diameter, sold for 75 French francs. When this was the price in 1929 (as seen on another publicity), it would correspond to approx. 53 Euro of today (2025). (see here.) The hands move together when the right one is turned, at any constant angle between them chosen by the operator.
