This is a VERY hard to find original Eisemann CM-4 base mount magneto. It was used on some early Caterpillar tractors and portable engines and possibly had other 4-cylinder applications. It is in great shape with no cracks, breaks, or repairs that I can see or know of. It is clockwise rotation and the impulse works as it should. Everything seems to work as it should. It turns over nicely with very little bearing wear. It has good magnetism and puts out a spark on all 4 leadouts. It would likely benefit from a good cleaning and/or a new condenser. Everything inside the top cover looks to be in great shape. It mounts on a 2 inch square bolt pattern and also on a 2 x 3 1/2 inch pattern and the mounting threads are in great shape. These original Eisemann CM-4 magnetos are almost impossible to find in the wild or even at swap meets so if you’ve been looking for one for an authentic restoration here’s a really nice one. Let the pictures be your guide. I can be reached at 262 573 193 1 if you’d like to talk about it.
