Transit Crated, British Home Office WW2 Era & 1962 Cold War Secomak Type 447 Portable Hand Operated Syren (Siren) By Service Electric Co Ltd Stanmore Middlesex & Tubular Stand With Original Instructions. Sn 18420 - 18420

An original WW2 era and cold war Secomak hand operated Portable Air Raid Siren with tubular metal stand, Type 447. This was produced by Service Electric Co. Ltd. Stanmore, Middlesex. This hand-operated siren (sometimes spelt 'syren') was intended for large or remote establishments such as R.A.F. airfields and large factories where the public air raid warning may not have reached. The siren consists of a simple bladed drum rotated through the use of the handle. The blades are angled so that air is drawn in through the holes in the ‘voice box’ casing, and forced out the side to produce a howling tone. In order to produce the fluctuating 'Action Warning' signal, the user let go of the handle and let the siren slow down before cranking up again to reach the high note. There appears to be very little documentation charting the history of the Type 447, but it would seem to originate in the late 1930's.This superb air raid siren, complete with stand is in excellent original condition. The siren is in perfect working order. The grey painted finish is in excellent condition. The removable steel arm with wood handle is undamaged. The siren has a metal grill over the rotating blades. This siren is very loud. It is designed to be unclamped and turned upside down within the stand for storage. The stand is made from tubular steel. The siren stands 33 ½” high overall when mounted on the stand. The siren is contained in its original wooden transit case with hinged lid. The lid secures to the frame of the crate by a fixed screw bolt with removable nut. The case fits the crate snugly. Due to size and weight delivery will be within the UK only & by arrangement at cost. Sn 18420
