This is a rather hard to find if not rare original Thordarson cast iron low tension ignition coil for an ignitor fired gas engine. These were used by International Harvester, Aermotor, and some other companies but will work for any ignitor fired engine. It is in excellent condition with no cracks, breaks, or repairs of any kind that I can see or know of. I checked it just before I took the pictures and it puts out a nice, hot blue spark that will surely run an engine. It’s been quite some time since one of these original Thordarson cast iron coils surfaced and I’m sure it will be a long time until another one does so if you’ve been looking for one don’t miss your chance on this one. Let the pictures be your guide. You’ll like it.
