Any Idea What This Could Be?

Picked this up at an estate sale. It was in a box of other misc. stuff

Looked all over the net and cannot find anything similar to it.

Thanks.

What is the name???? *****MLINE??? Looks like a mix of old and new - cable and yellow sleeve looks newer than the brass ends.... how is the cable fitted to the ends??? Crimped, plugs, soldered??

Shop made test probe of some sort, possibly for a ground resistance tester.

It's made up of 2 reducing couplings soldered to a copper tube and some brass rod.
