W48

Here we see a W48 of the 1955 DETEWE factory in ivory shade. There are two external differences that distinguish it from the production devices of other German factories is the sign that states the telephone connection number. The company logo is engraved and painted in black letters. And the number plate of fingerwheel, which is painted green with the numbers in silver. The base of the device is painted in ivory shade and we see the company logo printed, 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.
