In the early 1930’s having a bell separate from the telephone was normal practice. It was very usual for the “bell set” to be located in the hall, while the main telephone itself would be located convenient to the customer. It was also possible to mount the bakelite bell set underneath the telephone and this was then known as a “King Pyramid”.

The Tele 1/232 was a further development on from the Tele 162 and was introduced in 1934. It looked exactly the same but contained an improved ASTIC circuit that improved the sound quality of the telephone.
