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.

Introduced circa 1900 and the diagram can be found in the 1909 GPO telephone wiring book.

Made by British Ericsson as their model BC2000 and GEC as their model K8090.
