The basic balance scale has been around for thousands of years and its accuracy has improved dramatically over the last several centuries, the principle behind this tool remains unchanged. Its parts include a fulcrum, a beam that balances on it, a pan at the end of the beam to hold the materials to be weighed, and a flat platform at the other for the counter-balancing weights. Balance scales that require equal weights on each side of the fulcrum have been used by everyone from apothecaries and assayers to jewellers and postal workers. Known as an unequal arm balance scale, this variety builds the counterweight into the device. Counter scales used in dry-goods stores and domestic kitchens often featured Japanned or (blackened) cast iron with bronze trims. Made by companies such as Howe and Fairbanks, the footed tin pans of these scales were often oblong, some encircled at one end so bulk items could be easily poured into a bag. Seamless pans were typically stamped from brass and given style names like Snuff (the smallest) and Birmingham (the largest). Some counter scales were designed for measuring spices, others for weighing slices of cake. In the 18th century, spring scales began to appear and would use the resistance of spring to calculate weights, which are read automatically on the scale’s face. The ease of use of spring scales over balance scales. These scales are significant as they identify one of the basic preparation items for the weighing of foodstuff in the family kitchen to prepare everyday meals. This item is significant as it gives a snapshot into domestic life within the average home in Australia around the turn of the twentieth century and is, therefore, an item with social relevance.

The ease of use of spring scales over balance scales. One of the most common types of spring scales was the kitchen scale also known as a family or dial scale. Designed for horizontal surfaces, these vintage kitchen scales used the weight of goods in a pan at the top of the scale to force the spring down rather than the balance system. Such scales were common in early 20th century households and were sold by many companies. Many had flat weighing surfaces but some were topped by shallow pans. Companies such as Salters, Chatillon, and Fairbanks were the most popular brands used.

Black cast iron, medium weighing scales, with a fulcrum which the beam that balances on, there is as scoop at one end for the material to be weighted and a flat circular disc at the other end that holds the weights. Around the cast iron base is an embossed leaf pattern. All the weights have their weight embossed within the casting.There are 5 weights, marked 2 oz, 4 oz,8 oz,1 lb,2 lb, This scale does not have any visual markings on the arms to identify a maker or true balance. It is therefore assumed that these scales were made for domestic use only.flagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, spring scale, scale

These scales are a common type which would have been used in an industrial, farm or produce merchants of the day. many items were sold in bulk with little packaging. With a top weight of 30 lb, items weighed would have been bulky type items.The Avery company manufactured weighing equipment and scales from the 1730's. Scales of many different descriptions were used in sales over the years and these are a good example. These scales are painted black with a circular plate which is slightly dished. it has three chains attached to a metal bar at the top which is serrated and has a counter weight on it. Another attachment to the bar has the hook from which it would hang.The number 1 is on the counter weight.The serrated bar has graduated markings on it in half pound increments up to 30 lb.

Thaddeus Fairbanks (1796 –1886) was an American inventor. of heating and cook stoves, cast iron ploughs, and other items. His greatest success was the invention and manufacture of the platform scale, which allowed the weighing of large objects accurately. Fairbanks was born in Brimfield, Massachusetts, on January 17, 1796, the son of Joseph Fairbanks (1763–1846) and Phebe (Paddock) Fairbanks (1760–1853). His uncle was Ephraim Paddock, the brother of Phebe Paddock. In 1815 he moved to St. Johnsbury, Vermont, and set up a wheelwright's shop above his father's gristmill. In 1820 he married Lucy Peck Barker and In 1824 he built an iron foundry. his brother Erastus joined him to establish E. and T. Fairbanks, a partnership to manufacture heating stoves, cast iron ploughs a design for which he patented in 1826. In 1830 Fairbanks and Erastus became interested in the raising and processing of hemp. Fairbanks went on to patent a hemp and flax dressing machine and became the manager of the St. Johnsbury Hemp Company. He also built a set of scales that would measure large loads of hemp accurately, as there were no reliable scales at the time. Upon the success of building these scales, his brothers recommended that he make and sell these for general use.  Fairbanks' most famous invention then became the platform scale for weighing heavy objects. These are commonly known as the Fairbanks Scales, for which he patented his original design in 1830.  Before this time, accurate weighing of objects required hanging them from a balancing beam as a result, particularly heavy or ungainly objects could not be weighed accurately. A platform scale, if large enough, could weigh an entire wagon. By placing a full wagon on the scale, unloading it, and then placing it on the scale when empty, it became possible to easily and accurately calculate the weight and value of farm produce and other loads. In 1834 Fairbanks and his brother formed "E. and T. Fairbanks and Company" to manufacture and sell these platform scales. These scales were well known in the United States and around the world resulting in the company doubling in volume every three years from 1842 to 1857. There was a temporary slow down during the American Civil War, however, the business took off again after the war. Their partnership was incorporated in 1874 into a firm known as "Fairbanks Scale Company". These platform scales revolutionized weighing methods of large loads and have been in use ever since. Portable platform scales are found in almost every hardware store, physician's office, and manufacturing factory throughout the United States and the world. The first railway track platform scale patent was granted to Fairbanks on January 13, 1857, as Patent No. 16,381. In 1916 the company was purchased by ”Fairbanks, Morse and Company”. Ownership of the company has since changed several times, but Fairbanks Scales continue to be made in St. Johnsbury Vermont to this day. Fairbanks had received 43 patents in his lifetime with the last one at the age of 91. He died on April 12, 1886, and is buried at St. Johnsbury, Vermont, at the Mount Pleasant Cemetery. An early example circa 1900 of the first type of platform scales used in a grocery store. This design for accurately measuring goods that were sold over the counter revolutionised the weighing of goods throughout the world. Platform scale metal black with removable tray & pan.

This instrument measures elevation by sensing minute changes in barometric air pressure relative to a fixed datum point at sea level or a known elevation, such as the starting point of a major town during a road survey, and has an accuracy of +/- 20 feet when used in experienced hands. The finely divided scale around the perimeter of the face is marked from 0 to 6000 feet elevation and 25 to 31 inches of mercury (Hg) for barometric pressure The single fine counter-balanced hand or pointer rotates anti-clockwise with increasing elevation and decreasing pressure. The label "compensated" indicates that the instrument is constructed to compensate for the effect of temperature changes on the accuracy of readings.

Aerial photos were used to make maps of forest types, timber resources, to survey logging areas and regeneration, to mark boundaries of public land and new plantations, to identify new roads and tracks, as well as for fire suppression. Infrared film was sometimes used to monitor insect and disease attack. The images needed to sharp, with high contrast, and in a large format (most were printed in B&W on 9-inch by 9-inch glossy photographic paper) with at least a 60% overlap to enable stereoscopic viewing and with a 20-30% side lap to allow for aircraft drift. Preferably, the photo scale was close to the final map scale avoid to problems when enlarging and to reduce distortion. Something was needed to supplement the very expensive and infrequent large-area photography programs. From the mid-1960s Victorian foresters began experimenting with small format 70mm and 35mm cameras which proved simple, practical, cheap and flexible. It was found that any SLR camera could be used provided it had a good quality lens and fast shutter speed (preferably down to 1/1000 second). Motorised cameras with a large film capacity had obvious advantages and were essential when access to the camera was not possible during flight. It is also essential for the shutter to operate at low temperatures and those lubricated with silicones were recommended. Components of a typical FCV Divisional Office system included – A Hasselblad or Vinten 70 mm format aerial camera with a focal plane shutter which could be electrically operated. Interchangeable lenses to allow for different photo scales and flying heights. Several large film magazines, which were loaded in a darkroom, each with a capacity of 100 feet or approximately 500 frames. A remote control for the camera in single-shot mode or automatic firing at selected intervals of 2 to 50 seconds. It also needed a frame counter. A light aircraft was modified with an internal mounting for the camera to keep it level and steady. Often a hole was cut through the floor for the lens. The aircraft also needed an inbuilt 12 Volt DC battery to operate the motorised camera shutter. The front passenger seat was generally removed to improve access to the camera. An Aldis drift sight was also fitted. This might be likened to an inverted periscope and is used to determine drift, to facilitate accurate navigation along flight lines and to determine the exposure interval for stereoscopic overlap. This item is kept at Traralgon.Hasselblad 500 ELM camera with 70mm lens, film pack, motor drive and battery In 1964 Hasselblad started production of a motorized camera, the 500 EL The EL/M is a modified version of the EL, "M" means modified, "EL" electric. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when man first landed on the Moon. Almost all of the still photographs taken during these missions used modified Hasselblad cameras. forests commission victoria (fcv), forest measurement, surveying, mapping
