Welcome to the PF.

Can you tell us what it is? Do you know what it is and what it is used for? How big is it? Do you have more pictures from different angles?

It looks like a lamp which can be hung from a bar. The hanger on the left looks like it got bent out of shape.

It would be easier with more detail. Is it attached to the short stem, or is the stem even part of the thing? Are there ports on it? What is under the stem? Are there markings on it?

If the column is made of an insulating material, it looks like a version of some of the accessories used for Van de Graff generator demonstrations.

Looks like a telescope for a spectrum analyzer.
