TELEPHONE No. 59
Designed by British Ericsson, the Telephone No. 59 was originally used by the National Telephone Company (known as their NT 1). There were two different versions of this phone, one with the bells above the writing desk and one with the bells below.
This telephone supersedes the Instrument, Subscribers, Wall, N.T. No. 1.
Circa 1930 the Telephone No. 59 was fitted with a Telephone No. 164 for a handset and this was an interim modification as the original handset, Telephone No. 28, was a source of complaints about faint speech. It was eventually decided to replace the whole set instead offering the customer the choice of a Telephone No. 4 or Telephone No. 11. If the customer would pay the extra rental charge then they could opt for the Telephone No. 162.
A special version with a high output generator was also available for use on magneto Coastguard circuits. This was the Telephone No. 59A (Diagram C.B.S. 203).A Generator No. 4CO was fitted in the Telephone No. 59 (Mark NT 8).
There was also a version without the generator - See Telephone No. 69.
Introduced circa 1899 and also found in the GPO Stores Catalogue 1928.
