Compass, 1940's

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.

Parks Victoria - Wilsons Promontory Lightstation
Lamp, Aldis
... V 5A" On Bakelite plug on metal box;"EXTRA LOW VOLTAGE"... attached to inside of box;"EXTRA LOW VOLTAGE TRANSFORMER / MADE ...The lamps were pioneered by the British Navy in the late nineteenth century and introduced by the Royal Australian Navy after 1918, and continue to be used to the present day. Manufactured in 1960, the Wilsons Promontory lamp was provided to the lighthouse by the Department of Shipping for signalling ships but was also used for communicating with Cliffy Island, 18 nautical miles away. This type of lamp was renowned for its brilliant light, and lightkeepers from the two lightstations ‘used to practice their signalling with each other, as its effective use was reliant on precise positioning of the scope which is located on top of the lamp’. The inside of the case is imprinted with ‘RAN (Royal Australian Navy), and details on the lamp include a serial number, the date of 1960 and the initials of the Department of Transport, which at that time incorporated the Commonwealth Lighthouse Service. Another Aldis lamp and case with a date of 1960 is held at Cape Nelson and third lamp and case is at Point Hicks; (date unconfirmed but possibly 1943). A fourth lamp and case formerly at Cape Schanck disappeared from the collection sometime between 1995 and 2003.Aldis lamp and case (WPLS 0003.2; likely provenance) The lamps are not rare in museum collections however the Wilsons Promontory example has a confirmed provenance to the lightation and has first level contributory significance as a fine example of the Aldis lamps that were distributed to lightstations throughout Victoria and Australia.1. Handheld black signaling lantern with trigger mechanism. Glass front with inner reflective disc. Black electrical cord is attached with a two pronged plug at the end. 2. Black painted wooden box for transporting lantern. brass catch, leather handle. Grey electrical cord inside plus transformer. Hinged lid. The Aldis lamp is portable, hand held visual signalling lamp with trigger mechanism and inner reflective disk used for optical communication via Morse code. The concave mirror is tilted to focus the light into pulse signals. Larger versions of the lamp are fixed on ships or pedestals and have shutters in front of the device that are opened and closed to transmit signals.
