ATM TELEPHONE L.11186
STROWGER WALL AUTOMATIC TELEPHONES
Wall telephone, with integral bell, that's very much like the Siemens Brothers 366. Bakelite cased with standard GPO style circuitry. Generally fitted with an ATM Dial No. 24.
Used mainly in the UK on Private Automatic internal systems.
The Model L11186A2 was possibly used by the Hull Corporation Telephone department. It also used a stainless steel dial finger plate.
When opening the case, release the two screws on the front cover and then pull them towards you are far as they will go. They will not come out completely but if you do not pull them towards you then they will catch on the casing as the cover is swung open. When closing the case it is also important to ensure the screws are pulled out.
