Original Imperial Japanese WWII Hand Cranked Air Raid Siren by Yahagi British Military Maps FIELD'S IMPROVED PARALLEL and consistsOriginal Item: Only One Available. This is a rare functional Japanese WWII hand cranked air raid siren, which would usually be attached to some sort of stand. There are two bolts on the rear for attaching to a mount, but no mount is included. It is definitely larger than the hand held type, and has a large nozzle on the front to help with sound projection. It looks to be made mostly of what appears to be aluminum, or some other non ferrous alloy.
