This chronometer was made around 1936 and has been on display at Flagstaff Hill for over 40 years as part of the exhibit of the ‘Reginald M’, an Australian-built, 19ss, coastal trader vessel. A chronometer is an accurate mechanical instrument used for measuring time. It is constructed carefully to remain stable even under the changing conditions of seafaring life such as temperature, humidity and air pressure. The Master or Navigator of a ship could use the chronometer and the positions of celestial bodies to calculate the ship’s latitude at sea. In 1905 the business Chronometerwerke GmbH was formed in Frankfurt, Germany, to supply the country with high-quality mechanical chronometers and ship clocks for their maritime trade, making the country independent of other international suppliers such as those in England. In 1938 the firm was renamed Wempe Chronometerwerke. The business continues today. Its products now include its well-known chronometers, battery-powered ship clocks, ship’s bell clocks, barometers, barographs, thermometers, hygrometers, comfort meters to measure temperature and humidity, and wristwatches. The company also performs chronometer testing facilities for the State’s Weights and Measures office. The article written by Givi in July 2022 “The Basics of Marine Meteorology – a Guide for Seafarers” refers to the weather’s signs and patterns being repeated over and over, and the recording of these observations helps forecasters predict changes in the weather. The chronometer is an example of a mechanical navigational marine instrument in use in the early to the mid-20th century. The maker is significant as part of a German government initiative to be self-sufficient in the production of good quality marine technology. This chronometer is significant as part of the exhibit, the Australian-built vessel, 1922 coastal trader ‘Reginald M’, listed on the Australian Register of Historic Vessels and on display for over 40 years.Marine chronometer or marine clock, brass case, glass cover, Roman numerals, 24-hour numbers beside them.

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

E. R. Watts and Son, makers of theodolites and other surveying instruments, of 123 Camberwell Road, London. The company was established in 1856 by Edwin Watts at twenty-three he had saved £100 from his earnings to start the business with his staff consisting of one boy and later Alexander Clarkson as an apprentice with the workshop a small room over a Bemondsey stable. Watts' first order was from Negretti and Zambra for a mining dial Alexander Clarkson In the early days the firm worked mainly on marine compasses. Edwin Watts would go down to the Docks to adjust the compasses once they had been installed on the ships. In May 1873 the business moved to larger premises a house with a garden. The workshop was also the home of Mr and Mrs Watts and their five sons and three daughters. By now there were fifteen to twenty men employed by the firm. The company were commissioned to supply the Theodolites and Levels for the construction to the Canadian Pacific Railway in 1881. Towards the end of the century, the firm began to make heliographs continuing to produce them for the government until just before the Second World War when by agreement assigned their manufacture to another firm. 1904 The first dividing engine was completed by George William Watts. It was so remarkable an instrument at the time and for years afterwards, In 1907 Arthur Ames went to Canada and started an organisation in Winnipeg in 1909 this became a separate company called E. R. Watts and Son Ltd. of Ottawa. This firm developed considerably and was eventually with the co-operation of three other instrument companies (Cambridge Instrument Co, Ross, and Negretti and Zambra), were reconstituted as ”Instruments Ltd” of Ottawa and Toronto. During the next ten years, the firm expanded greatly to include glass grinding, leather work, dividing and engraving, testing, adjusting and packing. This expansion was continued during the First World War when workshops were completed and the machinery installed and running within eleven weeks from the start of construction. During the war, a Sergeant Coles, among the rats, lice and mud of the trenches, fitted various bits of scrap into his cocoa tin and made the first Flash Spotter for plotting the positions of enemy guns. Coles was rushed home to the firm's factory where he and George William Watts designed a spotter not made out of a cocoa tin and as a result, the Watts Vertical Force Variometer was developed during WWI. Other Watts instruments made in the First World War included the Light Mountain Theodolites which were taken on Mt Everest expeditions. In 1919 ER Watts and Sons was incorporated as a limited company and in 1939 G. A. Whipple joined the Board of Directors. Shortly afterwards, Frank Charles Watts died having been Chairman of the firm for over 37 years and seen it through the First World War with all its expansions and difficulties. He was succeeded by his brother George William Watts with the vacant post of Managing Director being filled by G. A. Whipple. During the Second World War, the company expanded further and the number of employees rose to well over 1,300. In 1946 Watts acquired 78% of Adam Hilger and the microscope maker James Swift and Son Who were Manufacturers of Theodolites, Levels, Alidades, Meteorological Instruments, Variometers, and many other types of scientific instruments Then in 1948 the company amalgamated with Adam Hilger as Hilger and Watts which was then incorporated as a public company.Naval Rangefinder with a vertical wooden handle, and an arrangement of optical lenses.

Stevenson screens were first introduced in Australia in the 1880s and were widely installed by 1910. The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting. A brass plate on the front of the screen has impressed inscriptions. The screen is Serial Number 01/C0032, Catalogue Number 235862.Stamped into brass plate "CAT.
