Henry Browne and Son Ltd, of Barking, made aviation and nautical compasses, clocks and dials. The company made compasses for aircraft notably, Spitfires, Tiger moths and Concord. Henry Browne was born in Lewis, Sussex in 1842 and died in Barking in 1935. His company was a well respected English instrument maker that had been making and selling fine quality compasses, ship's clocks, inclinometers, sextants, and chandlery items for over 140 years. It started in a factory in Brightlingsea, Essex and moved to Barking in 1929. The Trade Mark brand Sestrel was used on all their equipment. Their “Dead Beat“ compass design is well dampened serving to reduce oscillations. It is reported that this design compass was fitted to many Allied ships during WW II. The company went through a boom period in the 1970s but collapsed in the 1980s due to the popularity of cheaper plastic compasses over tradition brass ones. Over more recent years, there has been a consolidation of British instrument makers and the firm of Henry Browne & Son has changed hands a number of times. At last count, it became part of Lillie & Gillie of London in 1985 when John Lilley & Gillie Ltd acquires the assets of Henry Browne & Sons (Sestrel) Ltd, a major competitor for what may be the second time. The model name of Sestral came about via the following.Take first two letters of the word Sensitive then the firs two letter of steady and the firs three letters of reliable hence the trade name of "Sestral". Item relates to the second world war used in many ships of the time merchant and military, It reminds us of a time in our social and world history when most of the world was in conflict.Henry Browne and Sons “Dead Beat“ compass design is well dampened serving to reduce oscillations and was an innervation that many makes of compass of the time din't have as a result the "Sestrel" design was fitted to many Allied ships during WW II.A liquid-filled Sestrel compass, with a brass housing and gimbal ring, wired for an internal low voltage light to illuminate the compass card.

This analog voltmeter is quite a large (industrial type) apparatus which permits the easy monitoring of electrical variations within the large SEC Victoria Hydro Scheme's electrical generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro schemes was achieved from the mid 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce inclusion of skilled and unskilled migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years. This voltmeter is very significant to the Kiewa Valley as its use was introduced during the Kiewa Hydro Scheme. Although only a small apparatus it was part of the explosion of human resources into the valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both an industrial and a larger residential community. This evolution in the valley created a change, not only in the "physical" landscape but also the socio-economic expansion which permitted other "tourist" based industries into the valley. This analog volt meter has two metal rods protruding from the "back" of instrument with screw on points for the negative and the positive leads allowing the "current" to flow across the calibrated resistors to indicate on the "face" side the strength of the voltage "power". The "face" of the instrument has a zero point and then five evenly graduated marks from Zero to the "100, 200 and 300" marked points of measures. A large "V" below these pointers indicates that they represent levels of voltage. Three small screws hold the "face" in place. At the back of the meter is an aluminium "clasp" with three protruding screws (positioning fasteners) and a a screw tightening fixture for the correct fastening of the "clasp" into the correction location on the meter "board".Manufacturer's logo "CSG" underneath "ITALIA"kiewa valley tourism, victorian alps, alternate energy supplies, alpine population growth

This resistor was part of the Hydro generator control metering system which displays what electricity is produced at the underground generators. The control centre can be hundreds of meters above the generators and this resistor reduces the large current to a small voltage entering a calibrated control monitor. This resistor is highly significant to the Kiewa Valley because it represents a major construction and ongoing operational industry dealing with the supply of hydro electricity to Victoria. Although it is relatively small in size it is part of the controlling mechanism for the supply of a non polluting energy source for home and industrial use.This mainly metal and wire resistor has been built of copper and brass and designed to carry a current of 2000 Amperes. Wires are wound around a non conductive cement block which has grooves on the top and bottom ledges to hold the wires snuggle into place. At the rear there are three connection rods which have long 5mm thick screws (to fasten cable ends)On one side it is scribed "0.2 OHMS" and underneath this "10 AMPS"kiewa hydro electricity scheme, victorian state electricity commission, transformers

This case is for a testing voltmeter recorder. The last time it was certified by SEC Vic laboratories on the 17/4/77. It was used extensively in the transportation of the mobile recorder which was sometimes placed for periods of one month at locations experiencing unacceptable fluctuations of power. These locations would cover the North East regions of Victoria. They cover voltage drops at domestic and business properties especially those that were experiencing regular fluctuations(daily) at approximately the same time of the day. As the electrical network is required to operate within a set level of voltage, fluctuations outside of this has to be investigated and necessary remedial action taken. This is especially so for rural properties where power "drainage" can occur through animal/bird and tree interference. See KVHS 0302 (A) for the instrument.This case for a mobile voltage recorder is very significant to the Kiewa Valley because it highlights the difficulties that can occur in maintaining a power supply that experiences fluctuating power demands by the rural industries that it supplies. The requirement of a mobile testing apparatus to cover the various sections in the Kiewa Valley and other rural areas in the northeast region is one of necessity as electricity once connected to a rural property is a labour saving supply as generators on rural properties require a higher degree of maintenance an ultimately at a higher cost. The testing of the SEC Vic supplied electricity to rural properties,those who had previously run on generators, had to be quick and unassuming with certainty of correct supply levels.This heavy and thick all leather case for the "easy" transportation of the Volt meter recorder has a opening top which pop riveted to the main body(rivets are aluminium). The all leather top has a shaped carrying handle which is also riveted on. There are two straps on the side of the top which can be fastened to the main body by metal "shoe" buckles. The bottom end is secured to the main bag by large rivets.Tick grade stitching is on all corners.Nilsec vic kiewa hydro scheme, alternate energy supplies, alpine growth in electricity consumption

This milli-volt meter was manufactured after 1950 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to measure very small voltages associated with the operation of the various Hydro Generators. The readings were able to be shown by the resistor in use in the current circuit. During this time period, high quality testing instruments were either sourced from Europe or England.This milli-volt meter is very significant to the Kiewa Valley as it was used by those electrical technicians, who were part of the Kiewa Hydro Scheme. An "off spin" from the Scheme was the beginning of an explosion in "human" resources into the Kiewa Valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both industrial and larger residential community. This evolution in the Kiewa Valley created a change, not only in the "physical" landscape(better roads and infrastructure), but also the socio-economic growth within the Valley allowing other "tourist" based industries to expand within the valley and Alpine areas.This millivolts DC meter was used in the 1950's. It is contained in a wooden box and has two coloured (red/black, positive and negative) screw tight knobs which have bake-lite connections. It also has a covered (black tin) view meter marked from zero to 10 millivolts. Underneath this and within a round bake-lite is a small adjustment screw. The top of the box is fastened onto the main structure by six brass screws. The back of the structure is fastened by eight brass screws and there are four small bake-lite rest knobs.On the face of the millivolt compartment , and at the top "TO BE USED WITH DIAL HORIZONTAL TEMP.
