I believe this gauge is correct for some GMC Trucks / Bus' / Coaches between 1947 & 1959.

I am often wrong, so please verify.

Good to Nice Cosmetic Condition.   Tested functional.

Body/Case diameter is 2".    Glass is curved.

Glass & Bezel were removed (and reinstalled) for cleaning.

I am happy to combine shipping.

Thanks for looking and Good Luck, Pete
