The solid-back microphones originally fitted to the Telephone No. 38 were mostly replaced with a Bakelite moulding containing a standard carbon microphone inset (these assemblies were made by Siemens Brothers). These refurbished telephones were known as Telephone No. 138AT. The CB version is called the Telephone No. 136. |
