IIRC,magnetos are pretty much a race car or race boat item. I have no idea if it is for a flat 6 Ford or not,but I suspect a web page devoted to old race boats would be the place to find out.
That's where Henry Ford made a "hand shake contract" with 17 year old Clay Smith that make him the youngest high performance consultant in the auto biz. Clay Smith grew up working in his father's machine shop,and was already grinding his own cams. He had one in the boat he was racing when Ford spotted him,and it was a flat 6 Ford turning over 6,000 RMS. Ford knew they weren't supposed to spin that fast and survive,so he asked Smith how he did it. That's when Smith told him about cross-drilling the crankshaft to increase oil flow. Ford signed him on on the spot using a handshake.
Seems like there were lots of Ford flat 6's in race boats,but not in cars.
