Item Description
This is the one non-ring item in the list but it is included as siren device is similar to those on a Japan made ring of the same time period. Binoculars are fully 3-D but with openings where lenses would be. Top has attached open framework containing blade that spins to make high pitch siren when blown into. About 50% silver luster remains. Working easily to produce ear-splitting shrill sound. Scarce.
