Old Champion plug

Eric in IL · Aug 28, 2017

I was looking for a 1/4 NPT pipe plug today. After about an hour of looking through my junque buckets, I went to town and bought one.

While looking I ran across this old Champion plug. Does anyone have a guess as to how old? The number on it is 1 CCM. It has a very thick wall on the threaded portion. I did not try to see if it would fire, but I bet it would.

I bet it is better than the junk they produce today.

I tried to look it up, but every reference that I found regarding it was aircraft, aviation. Know someone that had a plane maybe? The biggest spark plug that I ever held in my hand was one of the two in a Rumley "L" Oil Pull. That thing was absolutely huge. 3/4" or maybe 1" hole? I don't recall, but it was huge. I was bidding on it at an auction near me and we were trying to start it. Had a dead cylinder so I'm not sure it was bad that I was outbid.

The number is 1COM, looking closely, part of the O is rubbed off.

That crosses to a W14.

Didn't find any reference to what it fit other than "industrial application".

It's worth a little money if you could find a buyer.

On my older Gravely from the early 60s I need to use a short plug like that one. 5he hood will hit 5he top of a regular plug. Found a couple at the Hershey car show.

Thanks Steve, you are right part of the O is rubbed off.

Hmmmm, we used to have an old Gravely walk-behind with a sulky attachment. That might make this plug from the late 1960's ?

It appears that Champion 1 COM plugs cross reference to Autolite 3076 which fits John Deere Unstyled A's and B's.

from the 1930's.
the j.d. D used them also. and stationary engines. and the early mccormicks, like 10-20,15-30,22-36, w30. w40.

I have a couple boxes full of of old spark plugs. Whenever I see them cheap at auctions or flea markets I pick them up. I prefer the older take apart style so I can clean them or make two bad plugs into one good one. I use them in my antique engines. They work better than new plugs and look the period. The one you have I would say it is late 30's or 40's and looks to be in nice shape. I'm sure it would still work like new!

This spark plug is not an aircraft, aviation plug.

I have a JD D and it takes a larger plug that. My JD D has W-18 in it.
