Each contact or switch point is enclosed in its own ...This British made type "N1087" and code "N1087" C Ericsson auto flameproof telephone was used in the drum filling platform of the Golden Fleece Depot, in Hovell St., Wodonga. The type "N1087" and code "N1087" C Ericsson flameproof telephone was introduced in 1937 and certified by the British Mines Department as flameproof for Petroleum and Acetone Vapours, in 1938. It was designed specifically for outdoor use in areas where there may be exposure to inflammable vapours and hazardous chemicals such as petroleum. Each contact or switch point is enclosed in its own flameproof chamber, to reduce the risk of ignition and the volume of gas.The Ericsson auto flameproof telephone has local significance due to its use in the Golden Fleece Depot in Wodonga, as well as national and international significance due to its date and the rarity and relatively complete condition.Black Ericsson auto flameproof rotary dial telephone secured in a hinged cast iron case painted black. Rubber tubing connected to the bakelite handset and an adjacent metal plate with the name "Ericsson", type "N1087" and code "N1087 C", and certification of the telephone as flameproof with the letters FLP. "Ericsson" on the top left corner of the metal plate. "AUTO TELEPHONE / TYPE N1087 / CERTIFIED FLAMEPROOF / FOR GROUPS II & III / CERTIFICATE FLP. 2378" / CODE N1087 C" on the main part of the metal plate.ericsson telephones, british telephones, flameproof telephones, mining telephones, golden fleece depot wodonga, wodonga -

Melbourne Legacy
Document, Helpful Suggestions For Correct Procedure, 1988
This memo was distributed to Legatees as a guide to Legatees. When contacting widows, Legatees could follow the script to ensure that the important points were addressed. At the bottom of the page the document lists the number of phone calls made to widows and follow up visits to widows in need of a visit (1986 and 1987). Note item "k" in the document. The switch refers to the person manning the telephone switchboard. This person would make a written or mental note that the Duty Legatee was not available. Leaving a recorded message on the phone was not available at this time.That Legacy tried to ensure that all Duty Legatees could follow the same script. Technology for a message that popped up on the computer screen was not available at the time.White paper with black type of a memo about duty legatees.duty legatee, policies -

Equipment - Taillight relay and box, State Electricity Commission of Victoria (SECV), c1950
Item used to switch the power for the red tail lights circuit from the trolley pole to the battery circuit when the trolley pole was being reversed and not able to provide power to the internal and external lights. Made by the SECV. Salvaged from tram 14 during the project to renew the wiring and electrical arrangements of the tram. The box was located adjacent to the driver's windows and would click when the trolley pole was placed back on the overhead.Demonstrates an item fitted to a tramcar to switch an external battery tail lighting circuit.Wooden box made from softwood with bevelled corners, plywood top painted green containing an 8 Ohm "Post Office" type relay (see reference) fitted with two "break" contacts and associated insulated wiring soldered to the relevant contacts.
