Ash Wednesday Veteran This Bedford M Series tanker spent its working days at the Forests Commission depot at Gembrook, and among its many forays, fought the deadly Ash Wednesday bushfires at nearby Upper Beaconsfield and Cockatoo on 16 February 1983. Earlier in 1975, the M Series tankers underwent a design change at the Altona North workshops, replacing the cylindrical water tank with a “V” bottom 4090 litre water tank that sat low between the chassis rails to reduce its centre of gravity. Aluminium heat shields were also added to protect the pump operators on the back. While generally considered "bulletproof" the petrol fuel lines on this particular model were very prone to vaporise in the heat causing the motor to stall, often at the most dangerous moment.... in this case frightening the hell out of its driver, affable knockabout bloke, and firefighting legend Lex Wade. Some jokingly said this design quirk was an inbuilt safety feature to stop crews getting too close to the fire in the first place. The Gembrook tanker was later sent into the workshop and all its brake and fuel lines fitted with heat resistant lagging. Fortunately, this remarkable bushfire survivor was rescued from the scrap heap by Lex and fire equipment wizard Barry Marsden upon its retirement from a loyal and lengthy service. After a lick of fresh paint and most of its battle scars "buffed out", this time-honoured veteran now takes pride of place at the Altona North workshop.Bedford M series fire tankerMZF 347fire pump, fire tanker, forests commission victoria (fcv)

The Shire of Braybrook (1871–1951) was a vast, semi‑rural municipality stretching from Melton to West Melbourne, centred on the old Braybrook village at Solomon’s Ford. It transformed dramatically with the arrival of railways, the rise of Braybrook Junction/Sunshine, and the industrial boom driven by H.V. McKay’s Harvester Works. The area was first organised as the Braybrook Road District on 28th May 1860, after a public meeting at the Shamrock Hotel in Albion. The district was enormous, extending from Melton to Dynon Road on the West Melbourne swamp. Early settlement clustered around Solomon’s Ford on the Maribyrnong River, a key crossing for travelers heading to Geelong, Williamstown, and the goldfields. On 23rd January 1871, the Road District became the Shire of Braybrook. Council meetings were initially held in Maidstone, reflecting the early population centres. The Braybrook Shire Hall in Deer Park was built in 1885. That 1885 building was the first official hall and council offices for the Shire of Braybrook, long before the municipality shifted its centre of gravity toward Sunshine. It stood near the Deer Park Hotel and served as the administrative heart of the shire during the late 19th century. The Braybrook Shire Hall at Deer Park effectively closed as a council headquarters in 1930, when the Shire of Braybrook shifted its administrative centre to Sunshine. In 1951, the Shire of Braybrook was renamed the City of Sunshine, reflecting the shift of population and industry eastward. In 1994 - 1995 the Kennett Government reduced Victoria’s councils from 210 to 78, the largest restructuring of local government in the state’s history and this part of the City of Sunshine became the City of Brimbank. It is believed this extension table came from the Shire of Braybrook Shire Office located in Ballarat Road, Deer Park, opposite the Deer Park Hotel. Over the years this extension table was used in the Shire of Braybrook Shire Office Ballarat Road Deer Park, the Shire of Braybrook and City of Sunshine Memorial Hall Hampshire Road Sunshine and in the City of Sunshine Municipal Offices Alexandra Avenue Sunshine.

Information from Norman F. Dalton: Ballarat had a reticulated DC supply in the early part of last century and in 1905 had sufficient generating capacity to enable the trams to be changed from horse drawn to DC electricity. The use of electricity increased with the main power station located on Wendouree Parade, near Webster Street, under the ownership of The Electric Supply Company of Victoria. AC generating plant was installed in 1925 and conversion to AC proceeded. In 1934 the company was taken over by the State Electricity Commission Victoria (SECV) and more AC generation was installed and the changeover of customers was accelerated. This is around the time that the Synchronome Frequency Checking Mast Clock was installed at the Wendouree Parade Power Station. The SECV Annual Report of 1921 states: ::Section 11 of the act directed the COmmission to enquire into the question of securing the adoption of such standards of plant and equipment of a system, frequency and pressure for the generation and distribution of electricity as will admit of the efficient interconnection of undertakings throughout the State. In 1934 when the SECV took over the Ballarat operations the question of linking with the State grid had been a planned operation for some years but due to financial considerations had hindered it and in fact would continue to do so for a further 10 years. So while the need for close frequency control for interconnection was hardly an issue, the need to keep electric clocks correct was important, particularly as this item was a frequent sales point to cover the inconvenience and sometimes expense of converting from DC to AC. The clock is a very accurate pendulum clock with provision for varying effective length during operation for precise time regulation. There are two normal time dials and one is controlled by the pendulum and the other is operated by the system frequency. When the clock was in use it was installed by the MEter and Tests Laboratory and the time was checked daily by radio time signals. The two dials were repeated in the operators control panel in the Power Station. A maximum deviation between the two dials was set in the operating instructions (eg 5 seconds) and the operator would correct this when necessary by remote manual alteration of the turbine governor set point. The clock was used to drive and regulate a system of "slave" clocks which were used to display the time in various locations around the power station. A slave clock is a simple clock which is driven by a small electric motor, its accuracy is regulated by the master clock every 30 seconds to ensure that it and all the other slave clocks in the station are on exactly the right time; slave clocks were placed in various locations, from common rooms to workshops. A master clock could potentially run thousands of slave clocks at one plant. The clock also contains a rectifier. A rectifier is a device that is used to convert AC power to more stable DC current.Two clocks in a timber case. Both are electric, one is powered by the main pendulum mechanism, the other is a self contained electric clock. The main mechanism is of the gravity arm and roller type, which sends an impulse to the slave clocks every 30 seconds. The This Synchronome Frequency Checking Master Clock was used at the Ballarat Power Station. Below the main section of the case is a smaller cabinet containing a rectifier to provide consistent DC power for the clock. The rectifier was made by the Victorian company Hilco, which was located in Burwood. There is a high chance this is not the original rectifier from this clock as there appears to be brackets to hold a larger device in the space the rectifier occupies.Front below main clock face on front of case: "Patented Sychronome Brisbane" Lower left-hand clock face: "Frequency time" Lower right-hand clock face: "Standard Seconds" Synchronous electric clock mechanism on door (Frequency time clock): >200/250 V. 50~ >"Synchronomains" Made in England >Direction indicator for clock starting switch >"To start move lever in direction of arrow and release" >"Patent applied for" Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for main clock face: >"English Made" >"Patented" >Serial number "8751" >0 above right-hand pillar on front-plate Inside case, back panel, top enamel plate: >Seconds Battery + Pos. > Battery Common or - Neg. >1/2 min dials Inside case, back panel, bottom enamel plate: external seconds dial Inside case, right hand side, electrical knobs: two switches, both "A.C. mains" Pendulum rod, below suspension spring: Serial number (?) 0000005 Rectifier in bottom cabinet: >"Hilco Rectifier" >"A.C.
