Lot 6405

A water level gauge or tide-predicting machine of the German military navy

German Historical Collectibles from 1919 onwards | A82r | Live auction | 777 Lots


The small, portable device was developed by Heinrich Rauschelbach with ten tide drives for use on board to complement the extremely heavy, powerful computers in the Navy Department. It enabled the calculation of local water levels in remote sea areas for the next 15 days, which was crucial for submarines and minelayers. Approximately 20 of the hugely expensive calculators, costing 6000 Reichsmark, were probably made by Aude & Reipert in Babelsberg. The grey lacquered housing, with a 24 volt connection on the side, comes complete with the wooden transport box (the lock is defective). Not checked for completeness and functionality. Condition: II Questions about the lot?
