Jim, Ok the plug in ? has the later 30/31 shaped correct 3 X CORE only.. The base section has the later Mid 30s style knurling & it also does not go all the way to the bottom... IMO, Champion must have had many inner cores left over with the correct 3 & just used them up in the later style base.. I have quite a few U.S.A. made ones like that.. Last, No you can not take that 30/31 style core out & put it in the other type bases you show, it will not fit... It will if you can find the EARLY type Champion # 3 base... That is another story..

Fred, I guess these are different as well.......

They have the CORRECT cores for a U.S.A. 30/31, BUT the wrong style base as I explained before..

[Fred]

Hope this works ??

Another try @ this picture stuff... L to R.. NOS plug in Original box marked 1/29.. NOS plug with the correct 30/31 original 3 X core in later base, Small box.. Same as last one but bigger box.. Notice different gaskets.. And the # 3 NOT marked on the plug..

Fred, Marco and Tom, in alphabetical order,

I'm a little confused, is the core(porcelain) different in 28/29 vs 30/31? This is
for a " 3X " correct round top 3 plug. Yes, I know the shell's are different between
28/29 and 30/31. Is there some order of progression that I'm missing?

I just want the facts,............Thanks, Joe Friday

[Fred]

D.J. Yes on first Question.. You can not put a 1928/29 core in a 1930/31 base & vise virsa.. But it is a different story on the very early 1927 #3 plug & base..

Fred,
Could you/would you post a photo of them side by side,so I can see the difference.
Thanks, Dudley

BTW, thanks for posting the early EA horn wire connector.

This is the method I am using to take apart an early 3X plug. My question is can I apply heat as long as I do not heat it up to red or do I risk cracking the core?

As a Spark-Plug is a work of art. I love the 3x Spark-plug and never had problems with it. Lasts forever.

Here is a cut open pix of the 1928 Champion C-3 with extra points at the bottom for comparison to the 3X's. Sometimes less is more.....

Hello, I am trying to read your nice original chart for the Lincoln automobile. Does it list the Champion # 2 or a Champion # 3 plug for the Lincoln Car? Is this chart dated? Because the Champion X plug is prominently featured, I am guessing that this is during the Model T era 1909-1927, probably late. Circa maybe 1925 or 26? Do you have a reference for Champion plugs for 1928, 1929 or 1930 Lincoln cars? Please advise Best Regards, David Clement, 916 241 5079, or [email protected] Sacramento area.
