TELEPHONE No. 218

Introduced in 1933 this Bakelite cased C.B. or Automatic telephone was intended for use with Box, Coin Collecting No. 14 and various non-ASTIC Bellsets.

The induction coil was located in the Bellset with just a transformer inside the body of the telephone.

The telephone was supplied with just a drawer-less base plate.

The handset was called a Telephone No. 164.

This telephone was used with a Bellset No. 30.

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:-
