Some time ago when I was first getting started in this hobby I acquired a MightyMite with a dead coil. I was in the equipment rental business at that time and had a lot of sources for repair parts. NAPA had, and still has, a small engine division in their catalogs and I was able to get one of their paperback catalogs. (Incidentally you can get a paperback catalog for their marine engine division also and it is a wonderful reference tool for seals, coils, condensors etc.) In the catalog it has pictures for those of us who are impaired in mental vision 🙂 and I found what I thought would work, bought it and discovered it fit loosely on the laminates of the old coil. I used some thin cardboard to "fill in the gaps" and I had hot spark and still do after 30 years!.
In looking at that core once the coils were removed, I’m wondering if a small engine coil could be installed over the laminates on one side of the "V"?– or cut the laminates and fit in a coil from a single cylinder? I’m not sure a coil would have to be located in the center of that "V" to work. I think it would work regardless of its location. Fortunately you have something to experiment with that most of us don’t regarding RBM mags. The coil from a Johnson A or K series might fit perfectly in the recess and it is a single cylinder coil.
