W48

Here we see a W48 from the 1960 DETEWE factory in black. The only external difference that distinguishes it from the production devices of other German factories is the sign that indicates the number of the telephone connection. The company logo is engraved and painted in white letters. At the base of the device we see printed the company logo, the date of production and the serial number of production in white. We also notice that this device has a ground button which means that it operated in a call center.
