Instrument - Marine Telescope, 1870-1880
This telescope was amongst various items collected from a sea dive in Port Phillip Bay. The diver was the caretaker of the Port Lonsdale Lighthouse, who dived on various wrecks in the bay during the 1960's. After the caretaker's death, his son sold off many of the shipwreck artefacts. The telescope was purchased from the caretaker's son in the 1990's by a previous owner of the Marine Shop, Queenscliff, Victoria. John Browning was particularly well known for his scientific advances in the fields of spectroscopy, astronomy, and optometry. Between 1856 and 1872, Browning acquired provisional patents for designs of numerous scientific instruments. He was also the recipient of an award at the 1862 International Exhibition held in London. Also recognised for his temperature-compensated aneroid barometer. Browning's scientific instruments were used in physics, chemistry, and biology. The products he designed and manufactured included spectroscopes, telescopes, microscopes, barometers, photometers, cameras, ophthalmologist, and electrical equipment such as electric lamps. John Browning was born around 1831 in Kent, England. His father, William Spencer Browning, was a maker of nautical instruments. John Browning's great-grandfather was also an instrument maker as well as John’s brother Samuel Browning of the firms Spencer & Browning and Spencer, Browning & Rust, who also manufactured navigational instruments. The latter firm was in operation in London from 1784 to 1840 and was succeeded by the firm of Spencer, Browning & Co. John Browning initially intended to follow the medical profession and entered Guy's Hospital, a teaching hospital and a school of medicine. Despite having passed the required examinations, however, he abandoned his plans. Instead, he apprenticed with his father, William Spencer Browning. At the same time, in the late 1840s, he was a student attending the Royal College of Chemistry several days per week. By the early 1870s, practical optics had become John Browning's primary interest, and he listed his occupation as an optician on the census records from 1871 to 1901. He was well known among London's ophthalmic surgeons for his various ophthalmic instruments. He had a large part in reforming the art of crafting spectacles. Other achievements were as an author of the book, How to Use Our Eyes and How to Preserve them by the Aid of Spectacles. Published in 1883, the book included thirty-seven illustrations, including a diagram demonstrating the anatomy of the eye. In 1895, he was one of the founders of the "British Ophthalmology" the first professional organisation for optometry. He was not only its first president but also registered as its first member so many considered him to be the first professional optometrist. Other professional organisations he belonged too was as a member of “The Aeronautical Society of Great Britain”. In 1871 constructing the first wind tunnel located at Greenwich Marine Engineering Works. He was also a member of other scientific organisations, such as the “Microscopical Society of London”, the “Meteorological Society”, and the “Royal”. Then in 1908 the company of W. Watson & Son, opticians and camera makers, took over John Browning's company since 1901 John Browning had been semi-retired but in 1908 he fully retired and moved to Bournemouth in Hampshire. He died in Cheltenham, Gloucestershire in 1925.The telescope is significant for its association with one of the world’s leading scientific instrument makers and inventor of the 19th and early 20th century. It is believed the donation came off a wreck either in Port Philip Bay or between Point Lonsdale and the Nepean Heads making it a significant maritime historical artefact. Its provenance is good given it was taken off a wreck in this area by the Point Lonsdale lighthouse caretaker. Examples of John Browning's telescopes because of their scientific and historical importance are highly valued by collectors.Marine style single draw brass telescope with a sunshade. The single draw has no split and the second cartridge is held in a long brass tube within the single draw, mounted from the objective end. The eyepiece is flat and at the end of the first draw in a very faded engraving that is believed to read "John Browning, 63 Strand, and should read London under the word strand but this is hard to establish given the engravings condition. This interpretation of the engraving has been arrived at by examination of other John Browning telescope engraving examples."John Browning, engraved to the first tube in copper plate style "63 STRAND" Engraved under in capital textflagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, shipwreck artefact, port phillip bay, port lonsdale lighthouse, wreck, 1960’s diver, queenscliff marine shop, john browning, telescope, spectroscopy, optometry, scientific instruments, william spencer browning, optician, navigational instrument, microscopical society of london, aeronautical society, marine technology -

Instrument - Three draw Telescope, 20th century
This telescope was amongst various items collected from a sea dive in Port Phillip Bay. The diver was the caretaker of the Port Lonsdale Lighthouse, who dived on various wrecks in the bay during the 1960's. After the caretaker's death, his son sold off many of the shipwreck artefacts. The telescope was purchased from the caretaker's son in the 1990's by a previous owner of the Marine Shop, Queenscliff, Victoria. Many companies were making scientific instruments in Liverpool. Between 1730 up too today, they manufactured spectroscopes, telescopes, microscopes, barometers, photometers, cameras, ophthalmoscopes, and electrical equipment such as electric lamps. Liverpool was a major centre for the production of scientific items rivaling Glasgow and London from 1850 to 1920. This telescope appears to be of quality manufacture but the origins can only be surmised at based on the gold embossing to the leather surrounding the main brass tube as being associated with Liverpool England. There is no maker or owners mark, so again there is no sure way to determine the year of manufacture or maker. There were many opticians and scientific instrument makers working in and around Liverpool from 1730 through too today. Also the possibility the telescope could have been made outside Liverpool overseas should not be overlooked and may have been made as a souvenir item from Liverpool from the mid to late 20th century. The size and type of telescope is a traditional type that was used for many sporting activities in the mid to late 19th century for deer stalking, bird watching, or used generally. I believe the item dates from sometime around the early to late part of the 20th century as the use of the liver bird mark became popular in 1911. It began appearing on many manufactured items of the period up too today, denoting that these items were made by companies operating in or around Liverpool England. If the item had been made by a notable firm it would have been engraved with the makers name city of origin, or owner as was the accepted practice for these items. The writer has been unable to determine if any specific company had had exclusive use of the liver bird logo as it was widely used and was not copyrighted until the Liverpool football club successfully won a court case giving them the sole rights to the trademark in 2012.The item is also an example of the shipwreck artefacts gathered along the southwest coast of Victoria. It is also a sample of scientific instruments used up to the mid 20th century.Victorian style gentleman's three draw brass telescope with machine milling surrounding the end of each tube and around the objective end. The three tube draw has no split and all three cartridges are held within the main brass tube wrapped in leather with rope bindings at both ends 5 cm in length and beginning 7 cm from the objective end. The last 2.8 cm makes up the remainder of the brass tube which has a sliding brass sunshade. The eyepiece is flat and has a protective slide over the lens aperture. Two relay lenses are missing on the ends of the second and third tube. Gold embossed into the leather an inscription “Trade the Liver Mark” also embossed in gold a depiction of the mythical liver bird, associated with the city seal of Liverpool England. flagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, shipwreck artefact, port phillip bay, port lonsdale lighthouse, wreck, 1960’s diver, queenscliff marine shop, liver bird, scientific instrument, telescope, three drawer telescope, liverpool, liver bird trade mark, trade mark -

Inclinometer, Early 20th Century
Provenance not clear. Leather case has 'MMBW' inscribed in black pen, indicating an association with Melbourne Metropolitan Board of Works. Item has been in the possession of Terry McCormack since 1972Hand held brass pocket inclonometer level, circa 1920. Leather case for safe storage. Semi circular graduated dial with 90 degree vernier scale with a small (20mm) magnifying glass to aid reading the vernier scale. Above the body, mounted at the rear of the graduated dial, is a spirit level tube which is tilted by finger movement to the milled hand wheel. The height to be determined is sighted through the instrument eyepiece and the bubble tube is tilted until the bubble, viewed in the mirror inside the sighting tube, is brought level with the graticule sighted at the top of the subject object. An angle is thus obtained and by measuring the distance on the ground to the object, trigonometry can be applied to determine the height of the object.Herga & Co. BRISBANE. Made in England -

Leisure object - Stereoscope, H C White, Late 19th century
The development of stereoscopic photography views or stereographs was immensely popular in the United States and Europe from about the mid-1850s through the early years of the 20th century. First described in 1832 by English physicist Sir Charles Wheatstone, stereoscopy was improved by Sir David Brewster in 1849. The production of the stereograph entailed making two images of the same subject, usually with a camera with two lenses placed 6 cm apart to simulate the position of the human eyes, and then mounting the positive prints side by side laterally on a stiff backing. Brewster devised a stereoscope through which the finished stereograph could be viewed; the stereoscope had two eyepieces through which the laterally mounted images, placed in a holder in front of the lenses, were viewed. The two images were brought together by the effort of the human brain to create an illusion of three-dimensionality. Stereographs were made of a wide range of subjects, the most popular being views of landscapes and monuments and composing narrative scenes of a humorous or slightly suggestive nature. Stereoscopes were manufactured for various price ranges and tastes, from the simple hand-held device introduced by Oliver Wendell Holmes who promoted stereography through articles to elaborate floor models containing large numbers of images that could be flipped into place. The stereograph became especially popular after Queen Victoria expressed interest in it when it was exhibited at the 1851 Crystal Palace Exposition. Like television today, stereography during the second half of the 19th century was both an educational and a recreational device with a considerable impact on public knowledge and taste. The Fine-art Photographers' Publishing Co. published many stereoscopic pictures from many different photographers from around the world under license. They also not only sold these images of various scenes and of famous people of the time but also were retail sellers of the viewers with the subject item having been made in the USA probably by H C White who held the patent for the subject items design from 1895 to 1902.An item that was very popular from the mid 19th century through to the beginning of the Edwardian period. Used for entertainment and also educational purposes and significant as it gives us a snapshot into the Victorian era and its social and domestic societal norms.

Drift Recorder, W & G, A M Drift Recorder MKII, 1930 - 1939
Purpose built mechanical calculation machine for determining the drift of aircraft when operating in crosswind conditions. This device has an eyepiece and a prismatic periscope for viewing a distant feature being tracked. This device has calibrated rotary scales for height, speed (in KNOTS and MPH), and an adjustment to preset the 'crab angle' of the aircaft for cross wind compensation. The device can be opened for cleaning or maintenance purposes. Refer to the following extracts for information about bomb drift: "Crosswinds brought into the bombing problem a new factor, "drift" In order to fly a given ground track in a crosswind, an aircraft had to "crab" into the wind; the angle formed between the aircraft's true heading and its ground track was called the "drift angle" In a crosswind, the bomb would impact directly behind the aircraft and along its longitudinal axis at the moment of release. But this meant that the bomb would strike the ground at some point downwind of the aircraft's ground track. Thus, in order to score a hit, the bomber had to fly a ground track that ran upwind of the target." "Air resistance acting on a bomb after release caused it to lag behind the drop point and hit somewhere behind the bomber. The distance from a point beneath the aircraft at the instant of bomb impact to the point of bomb impact was called "trail." Trail increased as the bomber's airspeed increased or as its altitude increased. Furthermore, since different bombs encountered different resistance in the air, trail was also a factor of bomb shape."A. M. Drift Recorder MKII REF. No 6B/190 No 2668/41 X/ 3606 3E4H28 -

Equipment - Camera, The Junior Kromskop, c1899
The Kromskop (pronounced Chromescope) is one of the earliest commercial applications of colour photography, and was invented by Frederic Eugene Ives and announced around 1896, it is described in his English patent of 1895 and in a US patent of 1894. It was shown at a Camera Club in Britain in January 1896 and at the February Royal Photographic Society meeting, and was available for sale from early 1897. The Photochromoscope Syndicate was formed in 1896 or 97 to promote the viewer in Britain, and wound up in 1899. It was manufactured in south London.A monocular instrument used to reproduce colours, in a mahogany box The viewer combines stereo images from three-colour separation transparencies called Kromograms, these are viewed through red, green and blue filters. A Kromogram comprises three monochrome transparencies printed from three-colour separation negatives which are taped together. The order being red image, blue image, green image with a label and caption between the red and blue images. The red image lies horizontally on the top step of the viewer above a red filter, the blue image lies on the lower step above a blue filter, the green image stands vertically at the back of the viewer. The red and blue images are reflected into the eyepieces by transparent mirrors, these are coloured to absorb the light that they reflect to prevent a double image from the rear surface of the mirror, the mirror for the red image is coloured cyan/blue, that used for the blue filter is coloured green (the patent indicates a yellow filter). The green image is illuminated by a yellow reflector. As the mirror below the blue image is green there is no need for a green filter immediately in front of the green image. The viewer can be used in daylight, for some conditions a diffuser is used, this is hinged to the yellow reflector and laid across the steps. An artificial light was also available. The mirrors and image positions can be adjusted in the event that they become misaligned.
