Has anyone out there heard of the Edison Spark Plugs? I have a set of 6 new plugs in the origional boxes. They were made in West Orange New Jersey. The part number on the ends of the boxes state-S13. I have been interested in automobiles most of my life and this is the first that I have heard of the Edison Spark Plug. They must be back in the 30's somewhere by my way of thinking. Does anyone have a chart on them to know what they fit or approximately how old they are???

Edison Spark plugs were used in antique tractors. Made by, THOMAS A. EDISON INCORPORATED, AUTOMOTIVE DIVISION, WEST ORANGE, NEW JERSEY. They seem to be varied inprice. $3.00 to $10.00. But I don't know for sure how much they are worth. Not sure about the S-13 on the box, other then a part number, which I don't have a clue about.
