TELEPHONE No. 22
Wooden table telephone with trembler bell. More or less the same as the Telephone No. 20, except the this set has an upper gallery, which apparently does nothing technically, but makes the phone more ornate.
Also known as the Table Telephone, with Trembler Bell "B".
Introduced circa 1900 and the diagram can be found in the 1909 GPO telephone wiring book.
Early table telephones were connected to the internal wiring with a Strip, Flexible Cord Connection. Click here for more information.
