I was looking through a 1924 Edwards and Crist Co. parts and accessories catalog that contains about 60% bicycle parts but also about 40% motorcycle parts. One of the items caught my attention... a Auburn spark plug made especially for Hendersons. A quick Google search for images of a spark plug like this did not reveal any direct hits, so I am wondering if anyone has ever seen these.

Where they OEM specified or were they replacement parts?

Of course the Henderson parts books do not seem to specify make or model of many of the parts from other manufacturers they put on their bikes.

Just curious about this more than anything since it seems it has not been discussed here before.
