BELLSET No. 25 | ||||||||
Bakelite cased Bellset which superseded the wooden Bellset No. 1 but was similar electrically. Introduced in the early 1930's to match the new Bakelite cased Telephone No. 162. There was no rush to introduce this new bell set as the GPO had large numbers of the wooden Bellset No. 1 in stock.
Fitted with a capacitor (shown to the left of the bell ringer), a two winding induction coil (shown to right of the bell ringer) and a bell ringer. The ringer mechanism is a Bell No. 59A (twin 500 ohm ringer coils). The Bakelite covers were generally supplied in black, but could also be obtained in Jade green, Chinese red or Ivory. The Bellset is usually wall mounted and the cover was produced in plastic in the colours black, red, green and ivory. The covers were Part No. 1/SCO/1 Colour, the black being produced in Phenolic Resin, Type GX (Specs BS771 & S116) and the three colours in Diakon, Grade L.A. (Spec S116). Used on non-ASTIC telephones i.e. Candlesticks and Telephone No. 162 and No. 196. The Bakelite cased bell sets could be fixed under a 100 or 200 type table telephone. Special fixing screws are required which supplied as standard on the earlier bell sets. A Cord, Inst., No. 4/51H, Brown, 9" or Cord., Inst., No 5/22H, Brown, 9" would also be required. If a telephone is mounted on the Bellset then a Cord, Inst., No. 3/74H (Colour), 9" is required. Bellset includes (1946):- Bellset includes (1956):- Diagram - N525.
