Edison Spark Plugs

I recently picked up an all original 29 Tudor that runs. I noticed the plugs looked very old. They are Edison brand spark plugs. Has any one ever heard of them? Any info on them would be appreciated. Thanks, Dan.
 
35 yrs ago I bought a NOS set of 8 Edison plugs in the boxes.I used them in a 1915 Cadillac V8,but were same size as model A.
 
A couple of pics of the Edison Plugs. Note the number 37T stamped into the body of the plug. The number is present on both plugs.

Amazing info.:D I thought my like new Champion C16C's, with Rajah terminals were special, NOT EVEN!:(:( Bill W.
 
Thanks for the link Bill, I always enjoy your posts. Spark plug collecting is an addiction I was able to brake free of a few years ago, and reduced the collection to 100 keepers. It sure was fun when they were affordable. Here is a For-A-Ford plug that is one of my favorites.

Roadster62,
On my '30 coupe, with 6 volt alternator and stock distributor, I cut the ground electrodes off a set of 3X plugs, and drove it that way for a month. Ran good.---Bill W.
 
Those Edison plugs look really nice. I wouldn't mind a set, just to own them. I've never seen, nor heard about them.

I know they are not the factory plugs, but what number are the correct Edison plugs for a Model A Ford?
