NEW SURPLUS WWII era Champion Aircraft Spark Plugs still in their original sealed tubes! Please note the glue has dried out on some of the tubes and the label has fallen off. I have seen these advertised on as for use on Pratt & Whitney, Curtiss Wright and Allison WWII era Aircraft Engines. These spark plugs fit various WWII radial aircraft engines. I have been told they were used in the Curtiss Wright R-2600 Radial engine that was in the WWII B-25 Mitchel Bomber. They were also an early spark plug for the P-51 Mustang Allison engine. They were supposedly also used in the Pratt & Whitney R1830 and R-2800 radial aircraft engines. They are an early WWII era spark plug. As I do not have a cross reference chart for these R33S Spark Plugs, it is up to the buyer to determine if it will work for their application.
