Htf-2614PZ3 ii

Here we see a private telephone exchange—featuring four external lines and ten internal extensions—manufactured by the German company Telenorma in 1978. The model designation is Htf-2614PZ3 ii. The device itself is a greyish-green shade, while the handset is light grey; the handset cord is also grey. The unit is constructed from plastic, with the exception of the handset, which is made of Bakelite. The finger wheel is crafted from transparent plastic. The top two rows of buttons, labeled N1 through N4, correspond to the external lines, while the bottom two rows—numbered 1 through 10—correspond to the respective internal lines. The base of the device is made of plastic and features a sticker displaying the device model, year of manufacture, country of origin, production code, and, naturally, the company logo. On the back of the device, we can see the cable that used to connect to the central unit. Its dimensions are H: 12.5 cm, W: 25 cm, D: 19 cm, and its weight is 3,400 g.
