Here is a (mostly) complete mag, bracket and ignitor set up for a Waterloo Boy hit and miss engine. I only say mostly because I didn’t take it off and there may be some small parts missing. As you can see the tag says it is off a 5 HP Waterloo Bot. I (ASSUME) from a model H. It may or may not fit other sizes and models. The tag also says it was taken off 11/8/1969 55 YEARS ago. This came from a complete clean out that I did in the state of Maine. The was NOT a waterloo boy there so I assume it was removed for some service and then the engine left somewhere along the line. I have NOT tested this set up, everything looks good, but it is untested, and I cannot say if it will require anything before using it or not. The bolt hole spacing is Approx.
