Bell's Gallows Phone first patent spurred Bell and Watson to produce his first working model (The Mental Phone) on paper only. Later the Liquid Transmitter was produced. It is said this second patent beat Ilisha Grey by only a few hours, but this has been contested by Grey, who claimed it as his own.

This instrument was designated the No.16 by the British Post Office and was in use until the 1950's. It is based on an earlier design introduced in 1895 which looked almost identical and was supplied to the National Telephone Company. The example shown was made for the GPO as it is marked No.16. The transfers are almost certainly not original.

Used by the General Post Office as No 59, the box, made of Walnut contained 2 Dry Cells or Leclanche cells, as this phone was powered locally (LB local battery). The design was taken from the National Telephone Company, formed in 1885 from both the Bell & Edison Companies at the time. Similar to the Sterling U373 which has the handset at the side.

The Candlestick, used with bell set No 1A, replaced earlier golf ball style candlesticks, It was made by Western Electric and was first used by the National Telephone Company, taken over by the Post Office also as a No 2. The unit shown was manufactured by Sterling Telephone and Electric Company Ltd. Described as a central battery table telephone (pillar phone) having a solid black granular transmitter, with adjustable joint and enamelled brass base. No internal circuitry was provided other than the receiver hook switch, this was all provided in the bell box, which is connected to this instrument, (not shown).

A small wooden telephone used in offices or coal mines for one to one communication. Two units and a small battery is all that is required to work these units. Working with this instrument in coal mines could be a problem if there was gas around, never the less such units were seen in mines in the early days of Telephones. Strict rules would apply to their use but communication was as important as safety and the position of the instrument was carefully considered.

This type of back board and coin box was rented for installation in public houses and hall ways, originally designed by Hall Telephone Accessories Co Ltd around 1930, the design remained the same for over 30 years, only replacing the Tulip Mouthpiece and Butter Stamp Receiver with the Neophone Desk Set 232
