Ship's Daylight Signal Lamp/Searchlight, Circa. 1970
This is a fantastic vintage ship's signal/searchlight (sometimes called an Aldis lamp, named after Arthur C. W. Aldis who invented a widely used design) manufactured in October 1970 by Shonan Kosakusho Co. Ltd., Tokyo and Omori, Japan.
The lamp is constructed of brass and copper and has a 20 cm diameter reflector. Overall diameter is 27.8 cm (11") and it weighs 13.5 kg (30 lbs). It's mounted on a unique, varnished timber, floor standing tripod.
Operation of the signalling mechanism is via a toggle lever on the right hand side. This turns the globe on and off for the purpose of transmitting a morse code signal.
UPDATE: The searchlight has now been rewired and restored to full working order*. Spare 24V 60W bulbs are available (POA).
* A 24V power source is not supplied (POA). Operation from 12V DC is possible with the addition of a DC-DC converter (POA).
