This is a GPO Modem 2B. It is a 300 baud V21 modem. I've got 2 and hope to get them talking to one another! It is sitting on top of my ATE 25 line PAX.

Below is a Tele 250A. It is the same as a Tele 250 but with the addition of a socket for a headset. These were used as test sets by linemen. It is primarily for use on manual systems and has a local battery and magneto generator.

However, it can be used on auto systems as well, and has a dial and an internal buzzer (rather than a bell). The magneto handle stores in the lid when not in use. When you want to signal you open the small flap on the front and screw in the hanle.

Below is a Headset No. 2. This would have been used with the Tele 250A.

I have a later lineman's set, the Tele 704.

The Tele 704 is actullay bigger then the Tele 250A, but it is somewhat lighter in weight due to having a transistorised ringing generator rather than a magneto.

The B version of the 704 (which mine is) has a 20mA line current feed button, so it can be used for testing ordinary CB telephones.

This is my 25 line ATE PAX. This came from the Welsh Highland Railway courtesy of Ian Jolly. At the moment it is not doing much, but I've just got a new 50V power supply for it so it will soon be connected up to the Inspiration.

This is my 30 line STC PAX. This is an ex-hire unit and has been modified accordingly. All connections have been brought out to push-button connectors on the back panel. It has had carrying handles added to the sides, and also came with a beautifully made padded jacket!

The numbering scheme is: 1-8, 91-99, 901-909 and 9001-9004. Download the manual for this exchange here (500k PDF).

This is a rather nice Tele 314 with "Call Excange", "Bell On" and "Bell Off" buttons.

300 series telephones fitted with the "Call Exchange" button were used an shared service (or party) lines.

This is a Siemens Ediswan Centenary Neophone. It was the first telephone to incorporate a printed circuit board. Many people don't like these telephones, probably because of the production methods used - and I must admit that it does feel a bit like a toy. I think it looks great though!
