My neighbor just gave me a Fairbanks-Morse Type: F.M. XR6B16 magneto, serial# 3585786. I have no idea what the mag would go on, but it appears to be for a 2 cylinder engine, as there are 2 lobes on the points cam. Also, crudely stamped on the magneto case are the numbers 56989 and 12 degrees. I wonder if it isn"t for an older Deere D or something of the like. It has a bolt flange like on the mag for my Deere B if it"s of any help.

Thanks y"all for the help.

Does it run CW or CCW?

When turning it, which direction does it impulse? Any pictures of it?

The mag turns CCW, good impulse, good fire, everything. I don't have a distributor cap for it, though.

Most Mag have 2 lobes on the point cam as the magnets have to rotate 180 degrees between cylinder firings. A mag for a 4 cylinder engine is driven at crankshaft speed. if the engine is a 6 cylinder with a mag the mag is driven at 1.5 times crankshaft speed.
