Re: Champion 3X Plugs
Ok, here is your THIRD explanation! The lettering on the porcelain is quite red in color instead of the "orangeish" red found on production era plugs. It's my contention they were mid-late 30's. They however are not reproductions as the porcelains have the same bulbous shape as the early plugs which the "reintroduced" plugs never had.
