Thunderegg Agates are formed within rhyolite volcanic ash layers. They are rough spherical shapes, varying in size from less than an inch to over a metre long. Thundereggs usually contain centres of chalcedony which may have been fractured followed by deposition of agate, jasper or opal, either uniquely or in combination. A unique characteristic that these specimens have is the fact that they often look like ordinary rocks on the outside, but slicing them in half and polishing them may reveal intricate patterns and colours. These particular specimens are examples of thunderegg agates. Agate is a variety of chalcedony, a cryptocrystalline form of quartz. The agate component contributes to the intriguing internal patterns of the specimens. The specific locality of these specimens is unknown but they can be found in flows of rhyolite lava. They are formed in gas pockets in the lava, which act as moulds. These specimens can be found globally, with specific locations in Germany being particularly abundant. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.Two small solid specimens with pale, sandy-coloured exteriors and fractured internal patterns. burke museum, beechworth, geological, geological specimen, thundereggs, thundereggs agate, agate, rhyolite, rhyolite lava, volcanic ash, chalcedony, cryptocrystalline

Prior to carrying out a detailed condition report of the cetacean skeletons, it is useful to have an understanding of the materials we are likely to encounter, in terms of structure and chemistry. This entry invites you to join in learning about the composition of whale bone and oil. Whale bone (Cetacean) bone is comprised of a composite structure of both an inorganic matrix of mainly hydroxylapatite (a calcium phosphate mineral), providing strength and rigidity, as well as an organic protein ‘scaffolding’ of mainly collagen, facilitating growth and repair (O’Connor 2008, CCI 2010). Collagen is also the structural protein component in cartilage between the whale vertebrae and attached to the fins of both the Killer Whale and the Dolphin. Relative proportions in the bone composition (affecting density), are linked with the feeding habits and mechanical stresses typically endured by bones of particular whale types. A Sperm Whale (Physeter macrocephalus Linnaeus, 1758) skeleton (toothed) thus has a higher mineral value (~67%) than a Fin Whale (Balaenoptera physalus Linnaeus, 1758) (baleen) (~60%) (Turner Walker 2012). The internal structure of bone can be divided into compact and cancellous bone. In whales, load-bearing structures such as mandibles and upper limb bones (e.g. humerus, sternum) are largely composed of compact bone (Turner Walker 2012). This consists of lamella concentrically deposited around the longitudinal axis and is permeated by fluid carrying channels (O’Connor 2008). Cancellous (spongy) bone, with a highly porous angular network of trabeculae, is less stiff and thus found in whale ribs and vertebrae (Turner Walker 2012). Whale oil Whales not only carry a thick layer of fat (blubber) in the soft tissue of their body for heat insulation and as a food store while they are alive, but also hold large oil (lipid) reserves in their porous bones. Following maceration of the whale skeleton after death to remove the soft tissue, the bones retain a high lipid content (Higgs et. al 2010). Particularly bones with a spongy (porous) structure have a high capacity to hold oil-rich marrow. Comparative data of various whale species suggests the skull, particularly the cranium and mandible bones are particularly oil rich. Along the vertebral column, the lipid content is reduced, particularly in the thoracic vertebrae (~10-25%), yet greatly increases from the lumbar to the caudal vertebrae (~40-55%). The chest area (scapula, sternum and ribs) show a mid-range lipid content (~15-30%), with vertically orientated ribs being more heavily soaked lower down (Turner Walker 2012, Higgs et. al 2010). Whale oil is largely composed of triglycerides (molecules of fatty acids attached to a glycerol molecule). In Arctic whales a higher proportion of unsaturated, versus saturated fatty acids make up the lipid. Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007). Objects Made From the Whaling Industry We all know that men set forth in sailing ships and risked their lives to harpoon whales on the open seas throughout the 1800s. And while Moby Dick and other tales have made whaling stories immortal, people today generally don't appreciate that the whalers were part of a well-organized industry. The ships that set out from ports in New England roamed as far as the Pacific in hunt of specific species of whales. Adventure may have been the draw for some whalers, but for the captains who owned whaling ships, and the investors which financed voyages, there was a considerable monetary payoff. The gigantic carcasses of whales were chopped and boiled down and turned into products such as the fine oil needed to lubricate increasing advanced machine tools. And beyond the oil derived from whales, even their bones, in an era before the invention of plastic, was used to make a wide variety of consumer goods. In short, whales were a valuable natural resource the same as wood, minerals, or petroleum we now pump from the ground. Oil From Whale’s Blubber Oil was the main product sought from whales, and it was used to lubricate machinery and to provide illumination by burning it in lamps. When a whale was killed, it was towed to the ship and its blubber, the thick insulating fat under its skin, would be peeled and cut from its carcass in a process known as “flensing.” The blubber was minced into chunks and boiled in large vats on board the whaling ship, producing oil. The oil taken from whale blubber was packaged in casks and transported back to the whaling ship’s home port (such as New Bedford, Massachusetts, the busiest American whaling port in the mid-1800s). From the ports it would be sold and transported across the country and would find its way into a huge variety of products. Whale oil, in addition to be used for lubrication and illumination, was also used to manufacture soaps, paint, and varnish. Whale oil was also utilized in some processes used to manufacture textiles and rope. Spermaceti, a Highly Regarded Oil A peculiar oil found in the head of the sperm whale, spermaceti, was highly prized. The oil was waxy, and was commonly used in making candles. In fact, candles made of spermaceti were considered the best in the world, producing a bright clear flame without an excess of smoke. Spermaceti was also used, distilled in liquid form, as an oil to fuel lamps. The main American whaling port, New Bedford, Massachusetts, was thus known as "The City That Lit the World." When John Adams was the ambassador to Great Britain before serving as president he recorded in his diary a conversation about spermaceti he had with the British Prime Minister William Pitt. Adams, keen to promote the New England whaling industry, was trying to convince the British to import spermaceti sold by American whalers, which the British could use to fuel street lamps. The British were not interested. In his diary, Adams wrote that he told Pitt, “the fat of the spermaceti whale gives the clearest and most beautiful flame of any substance that is known in nature, and we are surprised you prefer darkness, and consequent robberies, burglaries, and murders in your streets to receiving as a remittance our spermaceti oil.” Despite the failed sales pitch John Adams made in the late 1700s, the American whaling industry boomed in the early to mid-1800s. And spermaceti was a major component of that success. Spermaceti could be refined into a lubricant that was ideal for precision machinery. The machine tools that made the growth of industry possible in the United States were lubricated, and essentially made possible, by oil derived from spermaceti. Whalebone The bones and teeth of various species of whales were used in a number of products, many of them common implements in a 19th century household. Whales are said to have produced “the plastic of the 1800s.” The bone of the whale which was most commonly used wasn’t technically a bone, it was baleen, a hard material arrayed in large plates, like gigantic combs, in the mouths of some species of whales. The purpose of the baleen is to act as a sieve, catching tiny organisms in sea water, which the whale consumes as food. As baleen was tough yet flexible, it could be used in a number of practical applications. And it became commonly known as whalebone. Perhaps the most common use of whalebone was in the manufacture of corsets, which fashionable ladies in the 1800s wore to compress their waistlines. One typical corset advertisement from the 1800s proudly proclaims, “Real Whalebone Only Used.” Whalebone was also used for collar stays, buggy whips, and toys. Its remarkable flexibility even caused it to be used as the springs in early typewriters. The comparison to plastic is apt. Think of common items which today might be made of plastic, and it's likely that similar items in the 1800s would have been made of whalebone. Baleen whales do not have teeth. But the teeth of other whales, such as the sperm whale, would be used as ivory in such products as chess pieces, piano keys, or the handles of walking sticks. Pieces of scrimshaw, or carved whale's teeth, would probably be the best remembered use of whale's teeth. However, the carved teeth were created to pass the time on whaling voyages and were never a mass production item. Their relative rarity, of course, is why genuine pieces of 19th century scrimshaw are considered to be valuable collectibles today. Reference: McNamara, Robert.

Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007). Objects Made From the Whaling Industry We all know that men set forth in sailing ships and risked their lives to harpoon whales on the open seas throughout the 1800s. And while Moby Dick and other tales have made whaling stories immortal, people today generally don't appreciate that the whalers were part of a well-organized industry. The ships that set out from ports in New England roamed as far as the Pacific in hunt of specific species of whales. Adventure may have been the draw for some whalers, but for the captains who owned whaling ships, and the investors which financed voyages, there was a considerable monetary payoff. The gigantic carcasses of whales were chopped and boiled down and turned into products such as the fine oil needed to lubricate increasing advanced machine tools. And beyond the oil derived from whales, even their bones, in an era before the invention of plastic, was used to make a wide variety of consumer goods. In short, whales were a valuable natural resource the same as wood, minerals, or petroleum we now pump from the ground. Oil From Whale’s Blubber Oil was the main product sought from whales, and it was used to lubricate machinery and to provide illumination by burning it in lamps. When a whale was killed, it was towed to the ship and its blubber, the thick insulating fat under its skin, would be peeled and cut from its carcass in a process known as “flensing.” The blubber was minced into chunks and boiled in large vats on board the whaling ship, producing oil. The oil taken from whale blubber was packaged in casks and transported back to the whaling ship’s home port (such as New Bedford, Massachusetts, the busiest American whaling port in the mid-1800s). From the ports it would be sold and transported across the country and would find its way into a huge variety of products. Whale oil, in addition to be used for lubrication and illumination, was also used to manufacture soaps, paint, and varnish. Whale oil was also utilized in some processes used to manufacture textiles and rope. Spermaceti, a Highly Regarded Oil A peculiar oil found in the head of the sperm whale, spermaceti, was highly prized. The oil was waxy, and was commonly used in making candles. In fact, candles made of spermaceti were considered the best in the world, producing a bright clear flame without an excess of smoke. Spermaceti was also used, distilled in liquid form, as an oil to fuel lamps. The main American whaling port, New Bedford, Massachusetts, was thus known as "The City That Lit the World." When John Adams was the ambassador to Great Britain before serving as president he recorded in his diary a conversation about spermaceti he had with the British Prime Minister William Pitt. Adams, keen to promote the New England whaling industry, was trying to convince the British to import spermaceti sold by American whalers, which the British could use to fuel street lamps. The British were not interested. In his diary, Adams wrote that he told Pitt, “the fat of the spermaceti whale gives the clearest and most beautiful flame of any substance that is known in nature, and we are surprised you prefer darkness, and consequent robberies, burglaries, and murders in your streets to receiving as a remittance our spermaceti oil.” Despite the failed sales pitch John Adams made in the late 1700s, the American whaling industry boomed in the early to mid-1800s. And spermaceti was a major component of that success. Spermaceti could be refined into a lubricant that was ideal for precision machinery. The machine tools that made the growth of industry possible in the United States were lubricated, and essentially made possible, by oil derived from spermaceti. Baleen, or "Whalebone" The bones and teeth of various species of whales were used in a number of products, many of them common implements in a 19th century household. Whales are said to have produced “the plastic of the 1800s.” The "bone" of the whale which was most commonly used wasn’t technically a bone, it was baleen, a hard material arrayed in large plates, like gigantic combs, in the mouths of some species of whales. The purpose of the baleen is to act as a sieve, catching tiny organisms in sea water, which the whale consumes as food. As baleen was tough yet flexible, it could be used in a number of practical applications. And it became commonly known as "whalebone." Perhaps the most common use of whalebone was in the manufacture of corsets, which fashionable ladies in the 1800s wore to compress their waistlines. One typical corset advertisement from the 1800s proudly proclaims, “Real Whalebone Only Used.” Whalebone was also used for collar stays, buggy whips, and toys. Its remarkable flexibility even caused it to be used as the springs in early typewriters. The comparison to plastic is apt. Think of common items which today might be made of plastic, and it's likely that similar items in the 1800s would have been made of whalebone. Baleen whales do not have teeth. But the teeth of other whales, such as the sperm whale, would be used as ivory in such products as chess pieces, piano keys, or the handles of walking sticks. Pieces of scrimshaw, or carved whale's teeth, would probably be the best remembered use of whale's teeth. However, the carved teeth were created to pass the time on whaling voyages and were never a mass production item. Their relative rarity, of course, is why genuine pieces of 19th century scrimshaw are considered to be valuable collectibles today. Reference: McNamara, Robert.

Prior to carrying out a detailed condition report of the cetacean skeletons, it is useful to have an understanding of the materials we are likely to encounter, in terms of structure and chemistry. This entry invites you to join in learning about the composition of whale bone and oil. Whale bone (Cetacean) bone is comprised of a composite structure of both an inorganic matrix of mainly hydroxylapatite (a calcium phosphate mineral), providing strength and rigidity, as well as an organic protein ‘scaffolding’ of mainly collagen, facilitating growth and repair (O’Connor 2008, CCI 2010). Collagen is also the structural protein component in cartilage between the whale vertebrae and attached to the fins of both the Killer Whale and the Dolphin. Relative proportions in the bone composition (affecting density), are linked with the feeding habits and mechanical stresses typically endured by bones of particular whale types. A Sperm Whale (Physeter macrocephalus Linnaeus, 1758) skeleton (toothed) thus has a higher mineral value (~67%) than a Fin Whale (Balaenoptera physalus Linnaeus, 1758) (baleen) (~60%) (Turner Walker 2012). The internal structure of bone can be divided into compact and cancellous bone. In whales, load-bearing structures such as mandibles and upper limb bones (e.g. humerus, sternum) are largely composed of compact bone (Turner Walker 2012). This consists of lamella concentrically deposited around the longitudinal axis and is permeated by fluid carrying channels (O’Connor 2008). Cancellous (spongy) bone, with a highly porous angular network of trabeculae, is less stiff and thus found in whale ribs and vertebrae (Turner Walker 2012). Whale oil Whales not only carry a thick layer of fat (blubber) in the soft tissue of their body for heat insulation and as a food store while they are alive, but also hold large oil (lipid) reserves in their porous bones. Following maceration of the whale skeleton after death to remove the soft tissue, the bones retain a high lipid content (Higgs et. al 2010). Particularly bones with a spongy (porous) structure have a high capacity to hold oil-rich marrow. Comparative data of various whale species suggests the skull, particularly the cranium and mandible bones are particularly oil rich. Along the vertebral column, the lipid content is reduced, particularly in the thoracic vertebrae (~10-25%), yet greatly increases from the lumbar to the caudal vertebrae (~40-55%). The chest area (scapula, sternum and ribs) show a mid-range lipid content (~15-30%), with vertically orientated ribs being more heavily soaked lower down (Turner Walker 2012, Higgs et. al 2010). Whale oil is largely composed of triglycerides (molecules of fatty acids attached to a glycerol molecule). In Arctic whales a higher proportion of unsaturated, versus saturated fatty acids make up the lipid. Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007).

A Sperm Whale (Physeter macrocephalus Linnaeus, 1758) skeleton (toothed) thus has a higher mineral value (~67%) than a Fin Whale (Balaenoptera physalus Linnaeus, 1758) (baleen) (~60%) (Turner Walker 2012). The internal structure of bone can be divided into compact and cancellous bone. In whales, load-bearing structures such as mandibles and upper limb bones (e.g. humerus, sternum) are largely composed of compact bone (Turner Walker 2012). This consists of lamella concentrically deposited around the longitudinal axis and is permeated by fluid carrying channels (O’Connor 2008). Cancellous (spongy) bone, with a highly porous angular network of trabeculae, is less stiff and thus found in whale ribs and vertebrae (Turner Walker 2012). Whale oil Whales not only carry a thick layer of fat (blubber) in the soft tissue of their body for heat insulation and as a food store while they are alive, but also hold large oil (lipid) reserves in their porous bones. Following maceration of the whale skeleton after death to remove the soft tissue, the bones retain a high lipid content (Higgs et. al 2010). Particularly bones with a spongy (porous) structure have a high capacity to hold oil-rich marrow. Comparative data of various whale species suggests the skull, particularly the cranium and mandible bones are particularly oil rich. Along the vertebral column, the lipid content is reduced, particularly in the thoracic vertebrae (~10-25%), yet greatly increases from the lumbar to the caudal vertebrae (~40-55%). The chest area (scapula, sternum and ribs) show a mid-range lipid content (~15-30%), with vertically orientated ribs being more heavily soaked lower down (Turner Walker 2012, Higgs et. al 2010). Whale oil is largely composed of triglycerides (molecules of fatty acids attached to a glycerol molecule). In Arctic whales a higher proportion of unsaturated, versus saturated fatty acids make up the lipid. Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007). Objects Made From the Whaling Industry We all know that men set forth in sailing ships and risked their lives to harpoon whales on the open seas throughout the 1800s. And while Moby Dick and other tales have made whaling stories immortal, people today generally don't appreciate that the whalers were part of a well-organized industry. The ships that set out from ports in New England roamed as far as the Pacific in hunt of specific species of whales. Adventure may have been the draw for some whalers, but for the captains who owned whaling ships, and the investors which financed voyages, there was a considerable monetary payoff. The gigantic carcasses of whales were chopped and boiled down and turned into products such as the fine oil needed to lubricate increasing advanced machine tools. And beyond the oil derived from whales, even their bones, in an era before the invention of plastic, was used to make a wide variety of consumer goods. In short, whales were a valuable natural resource the same as wood, minerals, or petroleum we now pump from the ground. Oil From Whale’s Blubber Oil was the main product sought from whales, and it was used to lubricate machinery and to provide illumination by burning it in lamps. When a whale was killed, it was towed to the ship and its blubber, the thick insulating fat under its skin, would be peeled and cut from its carcass in a process known as “flensing.” The blubber was minced into chunks and boiled in large vats on board the whaling ship, producing oil. The oil taken from whale blubber was packaged in casks and transported back to the whaling ship’s home port (such as New Bedford, Massachusetts, the busiest American whaling port in the mid-1800s). From the ports it would be sold and transported across the country and would find its way into a huge variety of products. Whale oil, in addition to be used for lubrication and illumination, was also used to manufacture soaps, paint, and varnish. Whale oil was also utilized in some processes used to manufacture textiles and rope. Spermaceti, a Highly Regarded Oil A peculiar oil found in the head of the sperm whale, spermaceti, was highly prized. The oil was waxy, and was commonly used in making candles. In fact, candles made of spermaceti were considered the best in the world, producing a bright clear flame without an excess of smoke. Spermaceti was also used, distilled in liquid form, as an oil to fuel lamps. The main American whaling port, New Bedford, Massachusetts, was thus known as "The City That Lit the World." When John Adams was the ambassador to Great Britain before serving as president he recorded in his diary a conversation about spermaceti he had with the British Prime Minister William Pitt. Adams, keen to promote the New England whaling industry, was trying to convince the British to import spermaceti sold by American whalers, which the British could use to fuel street lamps. The British were not interested. In his diary, Adams wrote that he told Pitt, “the fat of the spermaceti whale gives the clearest and most beautiful flame of any substance that is known in nature, and we are surprised you prefer darkness, and consequent robberies, burglaries, and murders in your streets to receiving as a remittance our spermaceti oil.” Despite the failed sales pitch John Adams made in the late 1700s, the American whaling industry boomed in the early to mid-1800s. And spermaceti was a major component of that success. Spermaceti could be refined into a lubricant that was ideal for precision machinery. The machine tools that made the growth of industry possible in the United States were lubricated, and essentially made possible, by oil derived from spermaceti. Baleen, or "Whalebone" The bones and teeth of various species of whales were used in a number of products, many of them common implements in a 19th century household. Whales are said to have produced “the plastic of the 1800s.” The "bone" of the whale which was most commonly used wasn’t technically a bone, it was baleen, a hard material arrayed in large plates, like gigantic combs, in the mouths of some species of whales. The purpose of the baleen is to act as a sieve, catching tiny organisms in sea water, which the whale consumes as food. As baleen was tough yet flexible, it could be used in a number of practical applications. And it became commonly known as "whalebone." Perhaps the most common use of whalebone was in the manufacture of corsets, which fashionable ladies in the 1800s wore to compress their waistlines. One typical corset advertisement from the 1800s proudly proclaims, “Real Whalebone Only Used.” Whalebone was also used for collar stays, buggy whips, and toys. Its remarkable flexibility even caused it to be used as the springs in early typewriters. The comparison to plastic is apt. Think of common items which today might be made of plastic, and it's likely that similar items in the 1800s would have been made of whalebone. Baleen whales do not have teeth. But the teeth of other whales, such as the sperm whale, would be used as ivory in such products as chess pieces, piano keys, or the handles of walking sticks. Pieces of scrimshaw, or carved whale's teeth, would probably be the best remembered use of whale's teeth. However, the carved teeth were created to pass the time on whaling voyages and were never a mass production item. Their relative rarity, of course, is why genuine pieces of 19th century scrimshaw are considered to be valuable collectibles today. Reference: McNamara, Robert.

Prior to carrying out a detailed condition report of the cetacean skeletons, it is useful to have an understanding of the materials we are likely to encounter, in terms of structure and chemistry. This entry invites you to join in learning about the composition of whale bone and oil. Whale bone (Cetacean) bone is comprised of a composite structure of both an inorganic matrix of mainly hydroxylapatite (a calcium phosphate mineral), providing strength and rigidity, as well as an organic protein ‘scaffolding’ of mainly collagen, facilitating growth and repair (O’Connor 2008, CCI 2010). Collagen is also the structural protein component in cartilage between the whale vertebrae and attached to the fins of both the Killer Whale and the Dolphin. Relative proportions in the bone composition (affecting density), are linked with the feeding habits and mechanical stresses typically endured by bones of particular whale types.

Although Lee DeForest invented the triode vacuum  in 1906, it was not employed in hearing aids until 1921. The first hearing aid using a vacuum tube was purported to have been made by Earl C. Hanson. He called his hearing aid the Vactuphone. It used one small peanut tube (below right) to amplify the output of a carbon hearing aid. The Globe Hearing Aid Company and Western Electric collaborated to manufacture the Vactuphone. By the early 1940s, Raytheon had developed miniature vacuum tubes. It was these miniature vacuum tubes that made body-worn hearing aids a reality. Unfortunately, the power requirements of these aids made it necessary to use two relatively large batteries—an "A" battery to power the filaments of the vacuum tubes and a "B" battery to supply the high-voltage for the plate current. The batteries were worn external to the hearing aid itself and the name "Two-piece" hearing aid was used to describe them. Until about 1945 "Two-piece" hearing aids were the norm. However, improved vacuum tube design reduced current requirements. As a result, battery manufacturers were able to reduce the size of the batteries used in hearing aids. At the same time, electronic components were also being miniaturized. This allowed the hearing aid manufacturers to design hearing aids with internal batteries. After 1945, these "One-piece" hearing aids quickly replaced the more cumbersome "Two-piece" hearing aids. With continuing improvements in both batteries and components, hearing aids continued to reduce in size until 1953 when the vacuum tube was suddenly supplanted by the transistor.Fawn plastic hearing aid with metal clip on back and wires leading from the bottom.

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.
