this BS pops up numerous times on the net and also at ATS but has been debunked many times..
An investigation by Pierre Stromberg and Paul Heinrich, with the help of members of the Spark Plug Collectors of America, identified the
artifact as a 1920s-era Champion spark plug, widely used in the Ford Model T and Model A engines.
SPCA President Chad Windham and other collectors concurred with his assessment.
Stromberg and Heinrich's report indicates the spark plug became encased in a concretion composed of iron derived from the rusting spark plug. Iron and
steel artifacts rapidly form iron-oxide concretions as they rust in the ground.
