GRAMMONT TYPE 10

Several French companies started manufacturing telephones in the early 1900s. I acquired this elegant model that carries the nameplate of a seller of electrical equipment, called G. Popelier. The telephone itself has been built by the company Grammont in Paris, using parts made by Eurieult. That name is engraved on the handset. 

The apparatus requires a local battery and an external bell. It has a second receiver. This was common with French telephones. It is often referred to as the "mother-in-law receiver". A button is pressed to call the operator.
