The telephone marked EURIEULT & Cie. originates from France, specifically from Paris, where the company was based at 12 Rue de la Tour. This type of apparatus was manufactured approximately between 1910 and 1925, and the Eurieult brand later became part of the Grammont company, renowned for its telecommunications equipment. It is a desk-type telephone in an unusually robust wooden housing with metal components and a separate receiver (actually two, to allow for eavesdropping). The telephone does not yet feature a rotary dial; calls were connected via a switchboard, typically operated manually by telephone operators. How did it work? The user picked up the receiver → which “rang” the switchboard. The operator responded → “Number, please?” The connection was made by manually linking cables on the distribution panel. These devices were designed to function as part of a switched system, rather than as standalone units with a dial.
