RESERVED FOR JEREMY MANN

This is a vintage T.C. O'Connell and Company AC Spark Plug with Coralox Insulator thermometer advertisement. This is a very rare piece the only other one I found sold in 2015 at auction for $485(reference last picture) but that's the only one I could find. Since that one is in great condition and this one is in good condition I've drastically lowered the price. This hung up in my shop for years and as far as I know this does work but I'm not sure on its accuracy. This will be shipped in a small crate for safety. outstanding for everyday use. superior materials and excellent craftsmanship ensure long-lasting durability.
