After the 1939 bushfires, the Forests Commission Victoria invested heavily in a radically new communications network. After suffering some inevitable delays due to the war, radio VL3AA switched into full operation in October 1945 proudly beaming out 200 watts across the State. But by today’s standards, the technology was primitive and the reception poor unless the user was on a high point somewhere. The radio signal was "line-of-sight" and bounced between fire towers and relay transmitters across the mountains back to the District offices. The advent of solid-state electronics in the 1960s replaced the more delicate valve sets which enabled greater use of vehicle mounted radios. The Commission continued to research, develop and build new radios at its many workshops around Victoria. The network was supported by a large team of skilled radio technicians. The more secure and versatile State Mobile Radio (SMR) digital trunk system came into operation in about 1995. Upgraded Tait Radios were purchased in 2014 after recommendations of the 2009 Bushfires Royal Commission. But it was the convergence of separate technologies such as 5G mobile phones, high-capacity and light-weight lithium batteries, Wi-Fi, the ever-expanding internet, cloud data storage, digital cameras, GPS, personal organisers and hundreds of supporting Apps into powerful smartphones and tablets which revolutionised bushfire communications from the mid-2000s. Manufactured in both UK and Australia, the 400 series telephone was developed for the PMG in 1957 based on the British, prototype, no.700, Bakelite phone. They became obsolescent by the early 1960s but because some magneto exchanges persisted in Australia for another quarter of a century and alternatives were not cost effective, PMG/Telecom regularly repaired or refurbished these obsolete phones until they were superseded by automatic exchanges.

In the early 20th century there were many small machines and instruments developed to use as home cures. These included massage and vibratory instruments and those taking advantage of the growing use of electric currents in the treatment of nervous and mental health issues. This machine was used to produce a electric current to use on the human body to alleviate ailments that included nervous conditions, neuralgia, lumbago, back ache, muscle soreness and even toothache. Developments in allied health treatment saw the waning of the popularity of these kinds of medical aids by the mid 20th century.This machine is of great interest as an example of the items used by people in the late 19th and early 20th century as home cures for all sorts of ailments that afflicted people at the time.This is rectangular wooden box with a lid connected with metal hinges. The inside of the lid has a paper insert with printed material on it. The box has a metal mechanism inside and this includes a metal magnet, a pulley with a rubber belt and two round metal drums covered in dark blue felt. On the outside of the box is a metal handle that is connected to the mechanism inside. There is a metal closing catch on the outside of the box. There are also two wires on the outside of the box with one of these connected to the inside mechanism. The wires have hollow brass cylinders attached to the ends. The box is heavily stained and scuffed.‘Magneto Electric Machine for Nervous & Other Diseases’allied health in early 20th century, warrnambool, history of warrnambool

Electric shock machines were used in the late 1800s and early 1900s by doctors who believed that electrical currents could treat various medical conditions. The efficacy of this treatment was doubtful. An 1890s magneto shock machine enclosed in a cedar box with instructions on the under-side of the lid. It is actuated by turning the exterior handle which is attached to two gear wheels, one of which has a cord belt that rotates a dual coil. Metallic wires are attached to two brass handles which when held in each hand conduct the current through the body.instuctions for use: "Newly invented improved Magneto-Electric Machine. Manufactured by Wiliam Skidmore Surgical Instrument Maker. Cemetery Road, Sheffield. Directions: Connect two metallic cord and wires with the sockets in the end of the box and apply the handle connected with the other ends of the metallic cords to any part of the person through which it is desirable to pass the current of electricity. Then turn the crank ... In applying it for the tooth ache, tic-doloreux or neuralgia ..."

Used by Ted Beddiscomb of Gormandale near Traralgon, brother in law of donor. Ted was a dairy farmer and used the motor for about 10 years to pump water. It is possible it was on his farm for some years prior to this.

Used to communicate with the local telephone exchange and for connection to other subscribers. The introduction of automatic exchanges saw the their demise. This phone was used in the family home of the donor at Caboolture (aboriginal for carpet snake) during the 1940s and 1950s.A magneto telephone for communication with a manual telephone exchange. The handle on the right hand side, which was turned to rotate the magneto to call the exchange - ask operator for a number and then to be connected. Telephone enclosed in a specially designed box for mounting on the wall. There was a bell on top which rang when the magneto ringer at the exchange was turned. Fitted with a carbon microphone mounted on the front of the box for the transmission of the spoken word and an electro- magnet. A receiver which hangs on the left hand side on a hook. The hook acts as the on and off switch to answer the call and to switch on the battery to provide power for the receiver and energize the transmitter. There is an angled ledge for writing any messages. There is no battery. The circuit for the phone is on the inside of the door to the interior of the phone. pHone is type CDA116 - PMG Registered - Ericsson.communication, telephonic
