Siemens & Halske W36 telephone
phone, developed in the 1930's and introduced at the Liepzig Trade Fair in 1936
was supposed to be the standard
German Post Office (Reichspost) set. The phone did not meet specification
of the Reichspost and was used by Siemens on PAX systems. The case and
handset are made of Bakelite. The digits 36 in the
designation W36 refers to the year of introduction, 1938. The
W38 was a development of this telephone.
Further advantages of the Model 36 (from sales leaflet)
The shape of the new telephone handset was developed as a result thousands
of head measurements. Microphone and telephone are positioned optimally between
the mouth and ear. The new telephone handset was shortened somewhat and has a
greater curvature. The handle is triangular in section and sits comfortably in
the hand. This new design gives no user fatigue, even in long conversations.
New cradle rest and dial
The cradle rest improves reliable operation by positively guiding the
handset into place. The dial is angled at a steeper angle for increased comfort
and improved legibility of the numbers.
Excellent stability even on smooth surfaces, is achieved by a good weight
distribution and the positioning of the rubber feet.
On request we can supply the new telephone with a flexible cord, which is
only half the normal length but readily stretches to twice its initial length.

How to wire a W36 to work on the UK plug and Socket system
- Remove the original line cord.
- Connect white of the new line cord to terminal b.
- Connect red of the new line cord to terminal a.
- On one tag of the capacitor locate the white wire - disconnect and
insulate this wire.
- Locate on the other tag of the capacitor a green wire - disconnect just
this wire and connect to one end of a 3.3k resistor.
- The other end of the resistor connects onto the capacitor terminal, where
the green wire was removed.
- Connect the blue of the new line cord to the same tag of the capacitor where
the new resistor is connected. This tag is becoming a little crowded
so it may be better to connect a piece of wire to the tag and then connect
the other end to the blue of the line cord and the resistor.
