I wonder if it’s some sort of anode/cathode for an electroplating process where that is connected to an electrical supply and suspended in the fluid bath?

Ah, yes! That sounds a definite possibility!

Could be lead/probe for instrument used for locating underground pipes and cables.
Looking at it could it be a forerunner of probe used in the Popie system to locate cable sheath faults.

Or alternatively used to give driving pupils who do not follow instructions a jolt.

I've emailed Popie to ask, thanks for the lead. 

I like the driving tuition aid though! 😂😂
