I'm looking to make up a set of 4 Edison #14 take-apart spark plugs, in good working condition. Does anyone have some extras they would like to sell? If so please PM me with a picture, thank you.
They're around, but scarce. Keep an eye on eBay.
Making a matching set can be frustrating. I have seen at least three variations for the Edison 14 I suspect there may be more versions than that?). One could easily have ten plugs before having four alike.
EBad does seem to be the place to find them. Although they can get a bit pricey on eBad.
I never have seen more than a few at swap meets.
