Bakelite Wall Telephones Type 311, 354, and 366

The Siemens Wall Telephones are now in very short supply

General Information Click Here

This series of wall phones were made by Siemens Brothers of Woolwich London from 1931. The Automatic Telephone Manufacturing Company also made a broadly similar device.

This range was made for private systems such as hospitals, but most were exported to be used in national telephone systems.
The 311 and 354 models generally date to 1932, and the 366, 1946 to 1951. They are all of similar appearance.

All these were exported to Canada mainly to the Provinces of Saskatchewan and Manitoba.

Wall telephones were much more widely used in North America than here in the UK. The GPO bakelite wall phones are much rarer.

Electrically the 311 is similar to a GPO 232 with its bell set 26.

The 354 and 366 models were probably not used in the UK, as they were designed for long distance work. Both have much higher impedance bells than the 311. The anti-side tone and impedance matching transformer also differed. This reduced losses while the telephone was in use, and provided more reliable ringing.

They all used a handset based on the Ericsson design for the GPO. The mouthpiece was different with a flatter design, than the conventional GPO mouthpiece.
All used a type 10 dial with markings appropriate to the Canadian market.

These telephones are included in the both the 200, 300 and wall phone sections as they range in date from 1931 to the early 1950's.
The hinged front enabling easy access to view the internals is a useful feature.
The bells are built in.
Note the flat mouthpiece differs from the usual curved GPO pattern.

Type 366 post-war from £250
Type 354 and 311 pre-war from £290
These telephones are now in very short supply.

I have a few original restored mounting plates at £10

The telephone does not have to be mounted on this plate, but it is a nice period touch.

If you have a telephone in your possession that you want to know more about, or have repaired or converted, please have it right next to you when you call. It is not sufficient just to have a note of any markings or to rely on memory. It may be useful to have a selection of small flat bladed screwdrivers to hand.
