Great garage sale find today. Can someone tell me about these gems? After some research, this set will be moved along. Sent from my SM-N960U using Tapatalk As found
Nice find. I don't collect spark plugs, but I do have 2 rare Signal Oil spark plugs and their boxes in my Signal Gas and Oil collection. Plain addicted to Signal Gas stuff. Anyone else collect Signal Gas? 1 more car I promise, Rex Winter Dry n windy Lubbock TX
I don't know enough to tell you any useful information but definitely worth the research. Some of those spark plugs are very, very early. Lou Manglass
