Wall mounted, wooden cased bell box.  The bell box comprises of a 1000 ohm magneto bell, 16c/s only (AC).

The Bell ringer is called a Bell No. 1A Unmounted and this, on it's own, is generally fitted to most wooden wall phones.

Normally fitted with matched bell gongs, but where a distinctive tone is required, the following combination of 2.5in gongs can be used:-
Bells-gongs No. 2 - Nickelled or oxidised.
Bells-gongs No. 2A - Nickelled or oxidised.
Bells-gongs No. 3 - Aluminium.
Bells-gongs No. 17 - Steel or bronzed with concentric hole.
Bells-gongs No. 12 - Cow gongs - cannot be fitted to Bells Nos. 1A or 59A.

This is a bell only and has no induction coil or other components.  Because of this it CANNOT be used as a direct replacement for a Bellset No. 1 or 25.

Therefore it should NOT be used as the only Bellset on a Candlestick or Telephone No. 162.  It can, however, be used as an extension bell.
