Photograph, Preparing to leave for the St George's Church of England Sunday School picnic, Mont Albert Road, 1922
The drags would have been leaving St George's Church of England in Mont Albert Road. The foundation stone for St George's Church of England, Mont Albert was laid in 1886 on land donated by Edward Dyer and the first service was preached in January 1887. From 1904 until 1907 it was known as Holy Trinity, Surrey Hills. The original church was weatherboard and replaced by a brick one in the Gothic Revival style which was designed by local architect George J V Blackburne, who also designed the Wesleyan School at Surrey Hills. The building was partly funded by donations, profits from a bazaar and concert, and other people donated furnishings. The church had boundaries along Mont Albert Road and St Georges Road. In 1998 the Church was sold and converted into a complex of units. Its current address is 19 St Georges Avenue, Mont Albert. The annual Sunday School picnic was held at Hampton and drags were the usual mode of transport. 'Lugano' was built in 1893 for William Wilson, a prominent stonemason and importer of marble fireplaces. In 1903 it became the home of William Holmes who was Chief Electrical Engineer for the Victorian Railways. He designed the electrification of the Melbourne suburban network. 'Lugano' stayed in the Holmes family until the 1930s. The annual Sunday School picnic was held at at a variety of locations and drags were the usual mode of transport. Donor information is that this was taken as the congregation prepared to depart for at Hampton on the picnic held on 25/2/1922. There are 2 copies: the original donated print and an enlargement. The original was mounted on card with photo mounts along with 506, 871, 872, and 873. It measures 13 cm x 9 cm.Black and white photo of 4 'drags' (horse-drawn hooded carriages) lined up in Mont Albert Road near the corner of St George's Avenue, in readiness for departure for the Sunday School picnic. The carriages are loaded with people and decorated with flags. The front carriage has a material sign attached to the side; the top line of writing is not decipherable, but the bottom one reads "SURREY HILLS". Four men stand in the road, which has bluestone curb and channelling. In the background is 'Lugano'.On rear in ink: "S.S. picnic to Hampton / 25th. Feb. 1922" and in a different hand in biro: "At Mont Albert.

Gramophone, 1911
Until late 1925, all record players reproduced sound by purely mechanical means and relied on a so-called "amplifying" horn to efficiently couple the vibrations of the stylus and diaphragm to the space occupied by the listeners. In 1906, the Victor Talking Machine Company, Columbia's arch competitor, introduced a line of models in which the horn and other hardware were concealed within a cabinet, made to look like fine furniture rather than a mechanical device. They named the new style a "Victrola". It quickly proved to be very popular and successful. Other makers, adopting the distinctive suffix, introduced their own "-ola" internal horn machines, such as Edison's Amberolas and Columbia's Grafonolas. They were soon outselling the external horn models. At first, like nearly all other early record players, all Grafonolas were driven by a spring motor that the user had to wind up with a crank before playing a record. In 1915, Columbia began to introduce electric-motor-driven models, as a majority of urban areas had been wired to electrical grids. The electrified Grafonolas supported both alternating and direct currents from 110 to 220 volts. Electrified Grafonolas never gained the popularity enjoyed by the spring motor-driven versions due to substantially higher prices and a lack of electrical service in rural areas. Grafonolas were manufactured under the 1886 United States Letters Patent No. 341,214 which Columbia Graphophone company acquired through its predecessor American Graphophone Company. Two models were available; a portable table model and bigger stationary floor model, offering limited mobility through the application of casters. The most notable table models included Grafonola Favorite introduced in 1911 and Grafonola Savoy introduced in 1915. The most notable floor models included Grafonola Symphony Grand introduced in 1907, Grafonola Regent introduced in 1909, Columbia Mignon introduced in 1910, Grafonola Princess introduced in 1911, Columbia Colonial introduced in 1913. Various period Grafonolas were introduced in 1917 to cater to an increasingly prosperous clientele. Columbia Phonograph Company began to manufacture a series of ornate, limited edition period machines. These were highly priced (some as high as US$2,100 ) special orders that provided consumers with options to choose styles which matched their interior décor. Although the Gramophone does not have a large monetary value, it is of social significance as it demonstrates the progress made in audio reproduction from the first Edison cylinder machines to improvements that allowed ordinary people to be able to buy music discs and enjoy music in their own homes. Gramophone with internal horn, floor model, mechanically operated by a crank handle. Colombian Grafonola Princess (Type F2) brand.

Waveform Ventilator, 1970
Professor Arthur Barrington (Barry) Baker was the first Australian anaesthetist to gain a DPhil in anaesthesia. He completed his DPhil at Oxford University at the Nuffield Department of Anesthesia in 1971, titled, Physiological Responses to Artificial Ventilation. The Waveform Ventilator is the machine developed to illustrate his DPhil. The waveform ventilator was used in several scientific studies on 'the effects of varying inspiratory flow waveforms and time in intermittent positive pressure ventilation (IPPV)', published in the 'British Journal of Anaesthesia'. Professor Arthur Barrington Baker had an extensive career in research and clinical practice including holding the position as the Nuffield Professor of Anaesthetics at Sydney university (1992 - 2005) and also as the Dean of the Australian and New Zealand College of Anaesthetists (ANZCA) (1987-1990).The variable waveform ventilator is of national significance, due to its association with Professor Arthur Barrington Baker (Prof. Baker) the first Australian academic anaesthetist, and the representation of historical social themes and research and design, in anaesthesia. Historic significance – It is a rare type of ventilator in good condition and well provenanced. It is a tangible record of the beginning of the long established and distinguished career of Prof. Baker, the first anaesthetist in Australia to gain a DPhil. Prof Baker has a strong involvement in the Australian and New Zealand College of Anaesthetists (ANZCA) organisation. The object is a product of Prof Baker’s Doctorate of Philosophy (DPhil) on respiratory physiology and is associated with the prestigious Oxford University and the well-known Nuffield Department of Anaesthetics. It also represents the social theme of migration to England from Australia in the 1960s and 1970s to access and experience academic and artistic opportunities limited in Australia at the time. Scientific Value – The object is of scientific value as it offers major potential for education and interpretation in anaesthesia. Although ventilators are common equipment, this specific design and construct prototype is one of a kind, designed and used specifically for research purposes. A rectangular shaped object on a trolley with four wheels. The top half of the object consists of two panels, one of cream coloured painted wood, the other black plastic, both containing several dials of different shapes and sizes. The wood surface also contains several gauges and a safety pressure clear plastic box. The plastic surface also contains a pin board. The bottom half of the object consists of two shelves. The whole object's perimeter is lined with perforated metals. The top wooden surface has several metal pieces of equipment and a long tube. The rear of the object contains numerous types of tubing and wire, a gas cylinder and two leather straps with buckles. The bottom half of one side of the objects has 3 electrical power outlets.Waveform Generator, Drs Colliss N Cowie, Dr Baker Dr Murray Willson, Dr Babbington, Safety Pressure, Error POS F/B, Position, Feedback, Set Balance, Reset, Full Stroke, Velocity, Converter Current, line Pressure, Low Pressure, Bias Pressure, Start, Stop, Stop, Reset Press, Max Press, W/G Output, A/CRO B/2.baker, arthur barrington, baker, barry, professor, academic anaesthetist, oxford university, nuffield department of anaesthesia -
