FeTap 756

Here we see a Siemens Fetap 756-1 telephone, manufactured in June 1978, in an orange shade. The first digit indicates that the device belongs to the 7 series; the second digit indicates the dialing method—in this case, the ‘5’ signifies pulse dialing; and finally, the third digit refers to the device’s equipment—here, the ‘6’ denotes specific features (such as a earth button, ‘a2’ shifting, etc.).
