As far as I know and searched in the web and specialized sites in slide rules and militaria this is the only existing Charpentier slide rule for sale made at "Taller de Precisión de Artillería" (Precision Artillery Workshop) from the Spanish Army between 1900 and 1930. in very good conditions considering its age and "use". It works pefectly and has minor signs of wear. Photos are part of the description.
I have added some other images that are proof of its authenticity. Take a look at the back seal and the gilded iron gate detail of the "Taller de Precisión de Artillería" and the curious differences with a general use Charpentier slide rule (last photo).
Probably used for field ballistic calculations and used during the Spanish Civil War (1936-1939).
An incredible find and an incredible piece for slide rules and militaria collectors.
Don't hesitate to ask me for additional information or photos.
