This is a very nice original magneto mounting shelf or platform for an old motorcycle or other one-cylinder application. It is in great shape with no cracks, breaks, or repairs of any kind. The magneto would mount on a 2 inch square pattern and all of the mounting holes are in great shape. It has some original plating on it as can be seen. It measures about 3 3/16 x 4 1/2 x 3/16 inch thick. The mounting holes or hold-down holes are about 4 i...nches apart on center. It has a "6" stamped on the bottom as can be seen. This had a Bosch ZE1 magneto on it that I have in another listing. These original parts are quite tough to find in the wild or even at swap meets so if you need one for an authentic restoration here is a real nice one. The pictures tell the story. I can be reached by phone or text message at 262 573 193 1 if you'd like to talk about it. Good Luck.
