Help me date a spark plug...

[Chibuya]

Well... I think it's a spark plug. Has the old A over C, Albert Champion logo. Dug several of these out of the backyard. I've checked the internet and none of the oldest spark plugs I could find have this much porcelain. Sorry, I took a pic of the one in the worst condition.

Thanks for your help,

Stacey

Im not sure how old it is but it is a spark plug, the metal threaded part rusts away and leaves just the part you have.

I am not sure, but that style logo & initials A/C might suggest that it is an early Albert Champion spark plug. If so, it probably dates to the late teens to early twenties.

guessing, 1908-1916

In 1908 with the backing of the Buick Motor Co., Champion began a new company called the AC Spark Plug Company. Albert Champion was appointed president. In 1916 Alfred P. Sloan formed United Motors Corp. and eventually acquired Buick and AC Spark Plug.

On October 27, 1927, Champion died of a heart attack. General Motors purchased the remaining stock held by Champion's estate and took over the AC company. On December 1st of that year, AC became a full division of General Motors. In 1971, United Motors Service was renamed United Delco Division. A few years later United Delco and the AC Spark Plug Division combined to form the company we know today as AC-Delco. To this day Albert Champion's name lives on with every AC and Champion spark plug made.

It is a 3 piece take-a-part plug fron1909/1920, and were the same as the Champion "X" plug. They could be taken apart and cleaned. Tony

Interesting history! Thanks guys. I had a feeling it was from the early teens, I just couldn't find one on the internet with that much porcelain so I was a bit stumped.
