Lug wrench was what I meant, but this appears too light for that function. Also odd that it would say Edison for that function. I agree that it looks too shallow for a spark plug, but perhaps there were some with relatively stubby upper porcelain and terminal sections? Andy Well, actually lawn mowers and snow blowers have stubby spark plugs as you describe. Maybe Edison invented them too!! --Art ************************************** See what's free at http://www.aol.com.
