New Zealand Post Office
Telephone HB470

This is a Bakelite, Automatic, table telephone, effectively a BPO Telephone No. 162.

Designed and initially manufactured by Siemens Brothers in the UK.

The telephone has no capacitor, bell gongs or ringer and therefore requires a Bellset for it to function.  The Bellset is a model HB60.

The picture shows a Telephone fixed to a Bellset, but normally the Bellset would have been fixed to a wall.
