The donor recovered this navigation lamp before the 1980s from an old storage area in a South Melbourne factory where he worked. He asked about the lamp, but nobody there knew anything about its origin, and he was told that he could have it. This is a complete ship navigation lamp with its original oil burner. The internal red colour and shape indicate that the lamp was used for the port side of a vessel. The burner assembly is fixed to a removable tray, and the burner disconnects from the tank to allow fuel to be added. Light showing from the lamp is magnified by the polished brass reflector behind it, and the painted internal surfaces give the light its red colour. The lid on the chimney unclips for inspection purposes. The wedge shape of the lamp is intentional. It allows the light to be visible horizontally from up to a 112.5-degree angle, and to be invisible past that angle. The light's colour and position are part of the code of signals that inform viewers of the vessel’s position, direction of travel and status. The red lights indicate the port side of a vessel, green lights indicate the starboard side, and white lights are used on the masthead. From 1972, lights and signals on marine vessels are required to be fitted according to the International Regulations for Preventing Collisions at Sea. SEAHORSE lamp, made in Britain: The firm Bocock & Wilkinson was established in Birmingham in 1890 as an electroplate manufacturer. In 1900, Kelly’s Directory lists the firm as a ship lamp manufacturer. In 1910, the firm was listed Trading As “Seahorse” at 17 & 18 Mott Street, Birmingham. The firm later became Bocock & Son, and in 1932 was listed as George Bocock & Co. Ltd, and in 1973, it was still at that address. Ship’s navigation lamp: an original, galvanised metal, Port bow-side lamp. The wedge-shaped case has an arc front and two flat side panels that meet at the back, with a metal chimney and a swinging ‘C’ shaped handle on top. The curved, clear glass Fresnel has moulded ribs, top and bottom. The chimney has a hinged cap with a clip closure. One flat panel has a firmly attached, hollow rectangular channel for mounting onto a post or bracket. The other flat panel has a ‘D’ shaped, swinging handle, and slides upwards to access the burner assembly with its original brass burner. Concentric rings of ventilation holes are in the base. A removable tray, with ventilation holes on two edges, holds the round fuel tank and burner and the short post with the curved brass reflector. All internal metal surfaces, apart from the brass burner and reflector, were painted red sometime after the lamp’s manufacture. Inscriptions are embossed on the three brass plaques on the front; one has a rope design border and a seahorse emblem. Branded Seahorse, made in Great Britain, Ca. 1930s.

A marine foghorn gives an audible navigational signal to warn vessels of dangers, hazards and the presence of other vessels in fog conditions. The foghorn signal is a series of long and short sounds with short or long pauses between them. These common signals conform to a code called the International Regulations for Preventing Collisions at Sea and provide such information as whether the vessel is under sail or motor, large or small, aground or at anchor. The designs of foghorns vary but they all use a column of air to make a loud sound. Some use vibrating plates or metal reeds, others force air through holes in a revolving cylinder or disc, sounding like a siren, and some use a clockwork mechanism to open the valves that let the air into the horn. They are usually built to meet particular specifications e.g. U.S.C.G. (US Coast Guard). This Tyfon plunger foghorn has a horizontal handle attached to a vertical rod that moves up and down inside a cylinder. When the handle is plunged down, in a similar way to a bicycle pump, the air is forced out of the bottom of the cylinder into a pipe with a bell-shaped horn on the end, making a loud, low sound. The wider base of the cylinder helps to keep it stable. The original type Tyfon foghorns were manufactured in about 1910 by Kochums Mechanical Workshop (Kockums Mechanical Werkstad, Ltd.), Malmo, Sweden. The company was established in 1840, became a Limited company in 1866, and established a shipyard at the Port of Malmo, Sweden, in 1870. The civilian ship production in Malmo ceased in 1987. As well as building ships the company built large industrial and agricultural machinery and maritime goods.this replica foghorn represents the design of a Swedish, Tyfon model 1910. It is an example of the type of safety equipment used on marine vessels to signal other vessels and signal to land. Replica foghorn; portable marine, plunger operation. It has a brass cylinder and adjustable brass horn. The plunger handle and base are wooden. Inscriptions are on the plaque on the horn and moulded into the air intake.
