Is this odd device some kind of lightning arrestor or primitive fuse? Help identify Leave a comment

old electrical device

I found this in a junk box in an attic of a house built in the 1940’s. The original house owner repaired appliances and took stuff in trade, so it may predate the house. It is on a ceramic base.

It looks to me like some kind of lightning arrestor. If the cylindrical elements are wound coils, then I’d be fairly confident. Is it for early electrical connection or perhaps an early phone connection?

It’s solid, whatever it is. Anyone recognize it?
