TELEPHONE No. 88

Original model	Interim model

Known as `The Corporation Set' (because many were supplied to Municipal systems) this is the GPO version of the National Telephone Companies NT13 model.

The GPO model had a wooden top whilst the steel body was printed with a wood grain finish.  Whereas the private models had transfers on the front of the case the GPO version had an instruction notice frame.

The later GPO variant (shown to the right) had a Tele No. 164 as a handset.  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.

Diagram N188 (dated 1917).  The NTC version predates the diagram by at least 5 years.
