Picked up this item and have not been able to find out anything.

Looks similar to a Hedgehog in my collection. The Front Blue section is a hard foam.

Any information would be appreciated

I found out more information about this item on a youtube video.

SUBMARINE CLASSIFICATION AND TRACKING SYSTEM ( SCAT ) 1960s ANTI-SUBMARINE WARFARE NOISEMAKER 17074​


The tracking system is a number of magnetic devices which attach to the hull of a submarine and then create a mechanical clacking noise as the submarine moves through the water, using the hedgehog to deliver them. included are a few pictures from the video
