From time to time we find interesting antique or vintage items that prove to be very difficult to identify.

Recently I came across a finely carved small wooden item which seemed to have some sort of electrical connections and attachments.

Towards the bottom there seems to be an area cut to take 10 or 12 turns of fine wire which is now missing. The middle has a strange spring-loaded spoon-shaped object held by the spring against a horizontal thick wire rod.

There are 2 electrical contacts on the base and a number of small insulated holes in the top of the object. This object is only about 6” across.

I am totally unable to figure out what this is. I suspect it may possibly be part of an old antique radio but this is just a guess. Anyone have any ideas?
