BELL No. 1A & BELL No. 1A Unmounted
mounted, wooden cased bell box. The bell box comprises of a 1000 ohm
magneto ringer, 16c/s only (AC) and two bell gongs.
Two variants were produced, one with a bias spring and one without.
The Bell ringer mechanism is called a "Bell No. 1A, Unmounted" and this, on it's own, is generally fitted to most wooden wall phones and Bellsets. This Bell ringer was also produced with a Bias Spring and called the "Bell No. 1A, unmounted, with Bias Spring".
Introduced circa 1913.
The housing is called a Case No. 3.
Therefore it should NOT be used as the only Bellset on a Candlestick or Telephone No. 162. It can, however, be used as a simple extension bell.
Superseded by Bell No. 59A.
Drawing - 1796.
