These photographs were taken just after the McKillop's Bridge was completed after the flood damage. The current McKillop’s Bridge was built by the Country Roads Board in two stages between 1931-36, during which its height was raised after the original bridge superstructure was washed away in record floods of January 1934, prior to its original official opening. In its reconstructed form the original concrete abutments were turned into additional piers and the welded-steel trusses were cantilevered back over them to meet the new higher road approaches. It is sited at McKillops Crossing, named after pioneer overlanding squatter George McKillop who crossed here in 1835. This was a stock crossing place for almost a century before the bridge was constructed.

In October 2000, Council invited three artists from the region (Deborah Halpern, Matcham Skipper, Tony Trembath) to submit designs for a sculpture / public art work for the Eltham Town Square. The commission was paid for by supermarket giant Safeway (Woolies) as part of its supermarket permit, which required them to contribute to beautification work in the Town Square.This is the first of three parts. The 'Spirit of Nillumbik' is a celebration of the artistic spirit of Eltham and surrounding communities. Each area is identified through the flora and fauna represented in the panels. The work honours the many creative artists and architects, past and present, who have built homes and shaped lives and livelihoods with their unique creative spirit. Halpern describes her work as a public expression of their individual and collective visions. Halpern acknowledges these contributions to our hand-made history and the influence they have on the character and identity of Eltham and Nillumbik. Five picture and six woven balustrades each made out of welded steel / organic wrought iron and coated with wax. Imagery (flora - plants, landscapes and fauna - animals, birds, reptiles, insects) are all based on the local environment. There is also a relevant aboriginal presence amongst each of the panels. Each panel represents the different areas that make up the Shire. 'Water' for Warrandyte, 'Kangaroos' for Christmas Hills, 'Cockatoos and 'Valley Creek Flats' for Hurstbridge, 'Wombats', 'Bluetongues' and 'Possums' for St. Andrews/Kinglake, 'Orchids' for Panton Hill, 'Cows' and 'Grapevines' for the Kangaroo Gound Hill landmark.

This is a photograph of McKillop's Bridge probably taken just after its rebuilding. The current McKillop’s Bridge was built by the Country Roads Board in two stages between 1931-36, during which its height was raised after the original bridge superstructure was washed away in record floods of January 1934, prior to its original official opening. In its reconstructed form the original concrete abutments were turned into additional piers and the welded-steel trusses were cantilevered back over them to meet the new higher road approaches. "McKillops Bridge was Heritage listed due to its social and technological significance – the steel trusses' arc-welded construction technique was a pretty big deal in the 1930s. It was once an important route for cattlemen, who used the ford across the Snowy in the years preceding the bridge's existence"This is a pictorial record of McKillop's Bridge just after its construction.A black / white photograph of a wooden bridge across a river.

The first sculpture awarded the Shire of Eltham 'Art in Public Places' Award/Commission. The Judges were Inge King, Jenny Zimmer and Daryl Jackson. The work deals with the juxtaposition of suburban and rural surroundings. This scupture is a typical example of the artist's oevre of the period. This sculptre is site specific and refers to the nature of the environment. The colour - bushfire red / sienna - alludes to the history of fire in the urban/rural fringe and the title, as well as the sculpture's shapes, forms and material refer to the natural and local elements. Judges report noted: "The most vital and expressive work for the site...with a great sense of dynamic movement and vibrant colour. Its' abstract forms will enliven the surroundings and the urban and natural environment. This work is the most appropriate for the site and expressive of the dynamics of an evolving community in which artistic discourse and debate has always thrived." The work has acquired the status of a major landmark from the National Trust. The Breeze is an abstract work made out of welded steel and painted in enamel in bush fire red / sienna. It comprises a series of flat, cut-out shapes, interlocking at different angles, giving the impression of being hinged together rather than fixed. The work references nature and the built environment. Its geometric shapes suggest man-made structures within industry and suburban life, while rural areas can be identified by the organic flame-like shapes fanned by the wind. The circular cut-out in the eye mimics the sun, symbolising the intense heat of the Australian climate, while the colour red alludes to the history of bushfire within the urban and rural fringe.

Inge KING (26 November 1915 – 23 April 2016) Born Berlin, Germany Arrived Australia 1951 Inge King trained as a wood carver and studied at the Berlin Academy (1937-1939), Royal Academy London (1940), and the Glascow School of Art (1941-1943) . She moved to London in 1947 and began carving organic abstract forms in wood and stone. In 1949-50 she went on a study tour to the United States of America where she was inspired to work in metal . Inge King arrived in Australia in 1951 and she completed several large scale public works. Between 1961 and 1975 Inge King lectured at the Institute of Early Childhood Development, Kew. From 1976 to 1987 she lectured in Sculpture at Royal Melbourne Institute of Technology. She was a founding member of the Ceminal Centre Five group, and she actively lobbied architects, governments and State galleries to include modernist sculptures in their plans and displays. In 1991 Inge King joined the first National Trust of Australia (Victoria) Public Art Committee, advising on public art at risk and worthy of Trust classification. The Australian Women's Art Register describes Inge King as having been at the forefront of developing a non figurative vocabulary in Australian Sculpture. Welded bronzed steel sculpture painted black and red. This sculpture by Inge King was purchased in 1967 with funds raised by staff and students of Ballarat Teachers' College, a predecessor institution of Federation University Australia. During this era a collection was made which resulted in an annual purchase or commission of an artwork of note. The Federation University Art Collection features over 1000 works and was listed as a 'Ballarat Treasure' in 2007. Signed 'I.

Victoria Bridge is a riveted and welded steel Warren truss bridge over the Yarra River completed in 1884 to a design by Fraser & Chase following a controversial design competition held in 1880. Funds for the bridge's construction were provided by the councils of Collingwood, Hawthorn, Kew and Richmond. The contract was awarded to Mr P. Platt. Charles Rowand was officially appointed Supervising Engineer in 1883. The winning design was based on the theoretical work of William Charles Kernot (1845-1909) who campaigned for economy in public works design and the application of scientific principles in engineering. ... The bridge was widened in 1890 by the addition of a third line of truss on new piers on the up stream side to carry horse trams. Work commenced in 1914 to convert the horse tramway to an electric tramway by the Prahran & Malvern Tramways Trust, part of the Trust's extension of its tramway into the eastern suburbs between 1913-18. In 1915 the bridge was further strengthened to accommodate the extra weight of electric trams and widened by the addition of two six feet cantilever footpaths. During this period the Prahran & Malvern Tramways Trust erected two ornamental gantries over the roadway to support overhead wires for the electric tramway. Further widening and reconditioning of the bridge took place in 1933, including the addition of four new welded trusses, two intermediate and two on the outside. The latter were supported on new cantilevered truss cross beams attached to the top of the piers.

Tramcar component - possibly locking key - made from two pieces of cut steel and welded together and finished. A known unknown! Kym Smith advised - "11/6/2020 - It looks familiar, but I can’t recall exactly. I think is used as a locking pin to hold an internal panel in place, possibly the internal panels/frames that are on the interior side of the sliding doors, with the pin going through the top sill into the internal frame?" and 13/6 " I remember somewhere seeing a panel that has pins in the bottom that locate in holes in the floor, then the panel is pushed into place and the securing/locking pin used to hold it in place, with the panel having a square saddle that the pin goes through. I’m wondering if it is a kick panel under a seat? "trams, tramways, tramcars, components

The blacksmith leg vise is also called the "solid box vise" and is one of the most important tools in the blacksmith's shop. It firmly holds hot iron while it is hammered, chiseled, or twisted. These are the only vises that are designed to take this kind of use day in and day out. A small 30-pound blacksmith's vise can survive pounding that would wreck a much heavier cast iron bench model. Three things make a blacksmith's vice special. One is that they are forgings, not cast iron or ductile iron. The second is the leg that provides support to the floor or from a sunken post. The last is the hinge, while not a perfect way to construct a vice the pin joint is durable and can take a considerable beating. If sheared it is easy to replace. These things all combine into a tool that can take decades of heavy use and abuse. Most in use is one to two hundred years old.Some of these vises were made by specialists such as Atwood of Stourbridge England, Steel City and Columbian in the U.S. and others were made in anvil manufacturing plants such as "Mousehole Forge" and "Peter Wright" in England and "Fisher-Norris" and others in North America. The design of these vises right down to the last chamfer seems to have been perfected in the 1600s and remained more or less the same until the 20th century. The bodies are forged wrought iron or mild steel and they have hard steel surfaces welded into the jaws. The jaws have little or very shallow serrations which are generally worn off.Around the turn of the 20th Century during the hey-day of the blacksmith shop in North America, these tools were considered so standard a commodity that they were sold without reference to the manufacturer. Very few were even marked with the maker's name. Size is best defined by weight as there is some variation in jaw size from manufacturer to manufacturer. They were sold by the pound and are still best judged by the pound.A vintage tool used in a Blacksmiths shop during the early 19th century to the beginning of the 20th century.

Moulding Plane: A moulding plane is a specialised plane used for making the complex shapes found in wooden mouldings that are used to decorate furniture or other wooden object. Traditionally, moulding planes were blocks of wear resistant hardwood, often beech or maple, which were worked to the shape of the intended moulding. The blade, or iron was likewise formed to the intended moulding profile and secured in the body of the plane with a wooden wedge. A traditional cabinetmakers shop might have many, perhaps hundreds, of moulding planes for the full range of work to be performed. Large crown mouldings required planes of six or more inches in width, which demanded great strength to push and often had additional peg handles on the sides, allowing the craftsman's apprentice or other worker to pull the plane ahead of the master who guided it. Auburn Tool Company: The Auburn Tool Company is known to exist from 1864 to 1893. George Casey reorganized the firm of Casey, Clark and Company as a joint-stock company in 1864, under the company name of Auburn Tool Company. The 1865 New York State Census noted the firm as a manufacturer of the plane, plane irons, and skates. The production that year was listed as 30,000 pairs of skates and 35,000 planes along with 25,000 dozen plane irons. The plane irons carried the trademark "Thistle". Both skates and plane irons were made from welded wrought iron and cast steel. The Auburn Tool Company was among the five leading plane manufacturing firms existing in the mid to late 19th century USA. Others were: H. Chapin's Son; Greenfield Tool Company; and Sandusky Tool Company. Auburn Tool Company, with these others, was also a founding member of the Plane Makers Association, organized around 1858 to fix prices. Most of the companies tools were manufactured by prisoners and in 1866 the firm was outbid for prison labour by J M Easterly and Co. After losing the contract with the prison authority they constructed a new building and continued in the plane manufacturing business with private labour. The 1870 US Census reported the firm had 21 machines, driven by water power, employing 66 males, producing annual products valued at us$70, 000. After A. Howland and Company was dissolved in 1874, the Auburn Tool Company again resumed using contract labour at the State Prison until 1877. The Auburn Tool Company merged with the Ohio Tool Company of Columbus, Ohio, on Nov 14, 1893. Although plane manufacturing was continued at Auburn until after 1907, after this merger the firm went under the name of the Ohio Tool Company. A significant item from the mid to late 19th century that today is quite rare and sought after by collectors. It gives us a snapshot of how furniture was made predominately by hand and with tools that were themselves hand made shows the craftsmanship used to make such a unique item. It also gives an insight into how many manufacturing companies bid for the rights to use prison labour to make their products at this time in our history.

A clamp is a fastening device to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. The tool is for temporary use for positioning components during construction and wood working. There are many types of clamps available for many different purposes. Some are temporary, as used to position components while fixing them together, others are intended to be permanent. A C-clamp or G-clamp is a type of clamp device typically used to hold a wood or metal work piece, and often used in carpentry and welding. C-clamps or G-clamps are typically made of steel or cast iron, though smaller clamps may be made of pot metal. At the top of the "C" is usually a small flat edge. At the bottom is a threaded hole through which a large threaded screw protrudes. One end of this screw contains a flat edge of similar size to the one at the top of the frame, and the other end usually a small metal bar, perpendicular to the screw itself, which is used to gain leverage when tightening the clamp. When the clamp is completely closed, the flat end of the screw is in contact with the flat end on the frame. When the clamp is actually used, it is very rare that this occurs. Generally some other object or objects will be contained between the top and bottom flat edges.

A C-clamp or G- clamp is a type of clamp device typically used to hold a wood or metal work-piece, and often used in, but are not limited to, carpentry and welding. These clamps are called "C" clamps because of their C shaped frame, but are otherwise often called G-clamps or G-cramps because including the screw part they are shaped like an uppercase letter G. The fixed end is not adjustable so size is not variable. G-clamps are typically made of steel or cast iron, though smaller clamps may be made of pot metal. At the top of the "G" is usually a small flat edge. At the bottom is a threaded hole through which a large threaded screw protrudes. One end of this screw contains a flat edge of similar size to the one at the top of the frame, and the other end usually a small metal bar, perpendicular to the screw itself, which is used to gain leverage when tightening the clamp.
