When the GPO took over the NTC they
inherited all their equipment. The NT telephones were renamed as
"Instruments, Subscriber, Wall/Table, N.T. No. X. Many of these were made
obsolescent relatively quickly but some were subsumed into the equivalent GPO
telephone type.
This section is from the GPO Rate Book and the
descriptions are split into Table and Wall models.
