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.
