Default What Is This? Plug Adapter?
My father recently found this item. It looks like some sort of spark plug adapter, and has a Harley Davidson plug in it. Does anyone have any ideas?

If I'm badly mistaken that's a non foul rebuildable spark plug , pretty common back in the 30's to 50's . Used them in the old flathead motors and bikes .
