I have a Harman & Collins flathead Ford magneto. It is a 8R101 model. It has the two bolt flange. I believe this unit to have been a nos piece. I am selling it as is though as I have no way of testing it. Consider it needing redone. The reason I say it was never used is it has not bolt marks where it would bolt up and the factory paper tag is still in place. Has the Harman Collins rotor and all inside looks new. I do not have the adapter , but speedway sales them. The cap has a chip on the number 3 leg of the cap. The coil wire boot has a crack. Got this from a guy who's father raced flatheads. He said that it was bought but never used , as best he remembers. It was in dry storage on a shelf in his father's garage. I have many pictures if anyone interested I can text them or email them to you. Again I have no way to test it so sold as is , needing redone. I see no damage to the case or other issues or repairs. Asking SOLD shipped to lower 48 states.
