I do not know what this gauge originally came with.

Body/Case diameter is 2 1/16".

I am thinking perhaps a Tractor because of the short lead.

I am often wrong, so please verify.

Nice Cosmetic Condition.  Tested functional.

Glass & Bezel were removed (and reinstalled) to clean haze off inside glass.

Thanks for looking and Good Luck, Pete
I am happy to combine shipping.
