Found an old spark plug. Think it may have been to an old tractor. Would love to find out if anyone has seen one of these or heard of it. Two piece body, ceramic insulator is about an inch long, logo says Grand Rapids redline.will try to post a pic.
Thanks Tim

Google spark plug collectors--should be some sites with pix/info to check, might be worth enough to make the time worth while.
