I don't know which brand was factory shipped, but here is some info:

I have an image of an AC ad from 1923. It shows an AC 185MS for Henderson motorcycles. I've attached the image.


I also have a 1951 AC spark plug catalog and it lists AC O-6 for Henderson motorcycles. The Champion equivalent was 6M.

I will send a picture of this plug as well. In both cases, the plug has fins to provide better cooling for the air cooled engine.

I'm running Champion D16's in my 1931
KJ. Those are hot plugs
but the bike runs great on them.
