Re: Let's "spark" some conversation

I don't think it's a sparkplug, there's no threads to screw it in with..........NGE

Re: Let's "spark" some conversation

Looked at it with my loupe. Just a bunch of tiny spots. Doesn't look like it was printed on there.

I had a 29 chevy pickup with a straight 6 cylinder engine in it the spark plugs were giants. That is from an older engine like the one I had. You were able to take the plug apart and clean it. the part you have or the porcelain center piece came out by removing the top flange nut. I think I had to use an 1 1/2" socket to remove them.
But yes it is a spark plug and the date is at least the late 20's.

The photo is upside down and it is an old spark plug. Seems parts of it have long gone away. Hard to date it with out markings.

Re: Let's "spark" some conversation

I am thinking it may be a burner electrode for a heating system. It was found in the yard of an old hotel, so it could have been from a car or their heating sys. This could explain the lack of threads.
Still looking,

This shows it pretty good.

Re: Let's "spark" some conversation

Thanks Mick, Very cool video. That would explain the large amount of porcelain and no threads! Now I am really confused.
I'm on it...really want to figure this out.

Re: Let's "spark" some conversation

mtntrekr2 is right its an old automotive spark plug like the soot-proof used in model T
in the teens and 20s.
They can be taken apart or sometimes the threaded part rusts away leaving the part you have. I have some here in that condition but my cam batts are dead.

People some times the part that srews into the engine rusts off, which appears to what happened in the case of this spark plug.

I found a very similar spark plug last November. In California at the beach about 8" deep. It's encased in a rocky conglomeration. Feromy Google research I Id'd it as from a Model T. You can see most of the metallic portion as intact.

Wow, very cool Dr. Joe. Thanks for posting. A model T Ford plug is awesome. It will have a place next to the 5 "T" hub caps that I have found.

Champion X25 or aftermarket copy 1905/1930 three piece spark plug. Model T, Hit&Miss engines. What you have is the electrode part of the plug. Tony
