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).
