WTD Oil bath Thermostat

I know this is a long shot but I am after a working thermostat for an oil bath air filter. I think they were used on Ghia, Bus and Beetle 71ish?
Let me know if you have one and how much. I will pay the shipping to Bris.

To test the thermostat use a hair drier or hot water. The center pin should start coming out with a little bit of gentle heat. If not its stuffed.
I can be contacted via PM.
This is a pic of where it is located and what it looks like.
Cheers Brad.

why is there a thermostat in an oil bath air cleaner???

operates the preheat flap when ambient temp is cold enough to call for it
