No, I didn't put in a bid.

The guy selling it reckons 1930s, which looks about right from the photos.

Looks like maybe a (window) current transformer?

A wooden CT case!.
Now that would keep them nasty Eddy currents under control.

Trumpy — The true emeritus members of the instrumentation and physics community are spitting blood lately. What us young punks call "Eddy" currents are properly termed Edward or even more formally Edwardian Currents.   ;-)
