Bosch magneto for hit miss engine, early auto, tractor, not sure?? Mag is in good condition and ready to use. Leaving the mag with original patina, new owner can shine up if desired. This is a trip mag and not a rotary mag. High tension magneto means used with sparkplug engines. I tripped mag on the bench and gave a nice spark. I think Witte used these mags also. 1 5/8″ x 2 1/4″ bolt spacing for the treaded holes. 1 7/8″ x 3 3/8″ mounting spacing that bolts mag to bracket. Reads “BOA” on the front. If you don’t see a part you need listed, good chance I have it and haven’t gotten around to it yet so just check with me. Like I said I have done this a long time and try to list everything accurately to explain all the good and the bad. If you decide you don’t want it or find another one cheaper, I won’t take it back. For example if my measurements are wrong I would take it back. Check out my other items. Be sure to add me to your favorites list.
