Manufactured in the 1960s, this mobile emergency telephone exchange was fitted into a caravan. Part of the Shepparton Division State Disaster Plan, the caravan could be towed to areas affected by disasters to enable communications to recommence. The caravan remained in service until approximately 1974.Mobile infrastructure plays an important role in Australian communications, owing to the often remote and hostile environments in which Australians live and work. Exchanges such as this facilitated phone calls in the aftermath of an emergency, particularly for hospitals, police and other emergency services. Today, Mobile Exchange on Wheels (MEOWs), Cell on Wheels (CoW) and Satellite Cell on Wheels (SatCOW) - which provide temporary landline and broadband services, mobile phone coverage and service in areas without communications infrastructure respectively - are a critical part of emergency response procedures for natural disasters such as fire and flood. Though technology has progressed, the need for rapid service in remote areas remains a present concern of the communications service providers in Australia. This mobile service infrastructure is historically significant as an early example of a service which has evolved over decades, yet is still needed today. The exchange, as a representative example of a vehicle which would provide early-response in a disaster, is socially significant as a facilitator of critical communications needs in devastated communities: access to emergency services and contact with family and friends. The exchange itself, intact from its period of use, provides an insight into technology of the 1970s.Mobile emergency exchange housed in a caravan trailer on 2 wheel base, duralin body, steel tow bar, Caravan divided into 3 sections; the exchange room; the relay room and the main frame room.

The relay room has a sectioned door so half can open at a time. Room contains a cupboard with folding bench top beneath a curtained window. The opposite wall has a bank of batteries and transmission condensers; there is a shelf above window, one fluorescent tube and fuse boxes. Tiles on floor also. The main frame room contains many metres of coiled black covered cable, a black covered magneto wall telephone with 300 type handset; grey plastic jumper cords, a rack of termination points and wire with wasp nests attached.

The box is cleverly designed to give quick access to the parts inside, having a lift-up lid and a pull-down front. The components within appear to be a portable radio, power supply or power converter with batteries and a charger. The attached leather strap makes the equipment easily portable. The portable power supply is significant for representing part of the evolutionary change in communications. The unit connects the use of power and radio for communication with the ability to save the power in power packs or batteries, or to convert the power from one form to another.Power supply, portable, electric; circuits can be Parallel or Series. Batteries (6) fitted into a square wooden box. Box has two catches to secure the lid and two catches to secure the drop-down front.

c1881 Henry W Seely, of New Jersey, USA, designed and patented an electric sad iron for pressing and smoothing material. He continued to modify and improve his designs, with his partner Richard Dyer, and other electrical appliance firms, e.g Hotpoint, began producing these flat irons that could provide continuous heat by connecting via an electrical flex to a light socket and hence without the need for hot fires, ash, or burning hot handles. Women with access to an electricity supply were delighted and their ironing chore became much less arduous No heat was felt at all from the iron as it is all concentrated on the bottom surface. By the early 20th century enthusiasm was building for the new electric smoothing irons: clean, powerful, adjustable, and labour-saving. This c1935 Premier System 'Smoothwell' flat iron was used by a resident of City of Moorabbin and is an example of the progress made from the sad irons used by the pioneers that are displayed beside it.A "Premier Smoothwell" electric flat iron with switched control lead and original box, c 1935 On plate of handle attached to Iron ' HARRODS Ltd. / LONDON On attached plate at rear of iron ' The "SMOOTHWELL" / "Premier System" /.........
