[QUOTE="LoneStar, post: 114734, member: 585"] Thanks for the ideas. Mine looks to be a 459155, per the photo - it does have the hole with felt wick for oil, and a narrow slot (.154"). Not sure about the other, but it seems unlikely to be one of the two numbers claimed to be used with magnetos A through D. As Greg says, the wide slot only makes sense if it needs to rotate, and no KVF came with manual advance. (Side note - why was the slot for the abutment omitted if it's intended for manual advance?). Probably post-Lucas production, or for a different mag? I'm still puzzled by what could be the difference between the early and late KVF cam rings. It's the only part that's unique to the E & F magnetos. The end housing, "screw, cam fixing" and "pin, special, cam timing screw" are the same in all versions. (Not sure what both those last are - mine appears to have a single screw, threaded but unslotted, that engages the cam notch.) Maybe it's something trivial like the lubrication hole? Anyway, I've ordered a new one and we'll see how it looks - the vendor had no info on the two variants. I expect it will be a replica of the later one, as that was used on more machines.
