A very unusual version of the Siemens & Halske Modell 27 (aka the W28), especially made for the Gemeente Telefoon Amsterdam (Amsterdam City Telephone Company).
Before WW2 Amsterdam had its own telephone company, which later was absorbed into the PTT.
Most S&H Modell 27 telephones have the type designation Vsa tist 66. This telephone has a different designation, probably because the lay out of the electrical components is totally different from other Modell 27’s. Oddly enough the base plate is of the standard kind, with the bulge for the capacitor on the left side, while inside this particular telephone the capacitor is placed on the right side.
This Phone has a beautiful and wel preserved Amsterdam coat of arms on one side. The 2 other specimens of this telephone in my collection do not have this coat of arms (anymore?).
The Siemens date code at the underside give 1931 as the year of production. The date code inside the handset is for 1929.
The Rotary dial is a replacement. It is not manufactured by Siemens & Halske, but by TEFAG. On the back side there is a data stamp, unfortunately only partially readable: march 194x. This model dial was often used to upgrade CB telephones for automatic telephony. This may indicate that this telephone was once a CB-version, although the diagram does show a Rotary dial.
Besides the already mentioned adaptations, a number of parts have been replaced. As with many old telephones the cords, transmitter and receiver have been replaced. The Original rubber feet have been replaced by stick on felt discs, normally used for furniture legs.
Also the receiver cap has been changed for a newer model, to accomodate the more modern receiver. And finally the capacitor has been change to make the telephone suited for use on the then modern public telephone network.
All in all this is a very well preserved specimen and because of the unusual lay out and coat of arms very special and valuable. I hope one day to refurbish and clean it and to change the feet, cords and receiver cap for more appropriate ones. These parts that are on the telephone at this moment just do not look right on an 85 year old telephone.
