TELEPHONE No. 238


Bakelite table telephone for use with Bellset No's 33, 35 & 40 on coin box circuits in Manual C.B. and Automatic areas.

Supplied without a base, line cord or dial as different types of bases, cords & dials could be fitted depending on the type of call office installation.

No induction coil was fitted to these phones as the associated Bellset conatins the induction coil instead.

Terminal nuts are 4BA (Part No. 1/SNU/51).

The frame that supports the switch hooks, also has terminals and contact springs attached.  The contact springs came with either one contact or two contacts per spring. This telephone could use either - the parts numbers are as follows:-
Frame - Part No. 1/SSW/8 - one contact per spring (Springset Part No. 1/SSP/705).
Frame - Part No. 2/SSW/8 - two contacts per spring (Springset Part No. 1/SSP/709).

An extra terminal is also fitted to this frame on the Telephone No. 238.

Later telephones, repaired at the PO factory were fitted with cloth covered handset cords (as shown).

There appears to be a Mark 1, Mark 2 and Mark 3 variants of this telephone, but no documentation is available detailing the differences.
