You are bidding on a 1960's NOS 60 AMP Gauge , It is marked AC Spark Plug Div, This has been out in my grandfathers barn for at least 40 years, He thinks it is for a truck, The Numbers on the side are hard to read but I think I have it . 6473877. The glass is not scratched or cracked the chrome is great this fits a 2 in. hole,This looks a lot like a stewart warner gauge Sold as is Thanks
