Anyone know a source for the Distributor Plate (aka, Distributor Cap) for CM-4 Magneto? My present "Plate" is original and so weathered it is chalky on outside. The outside appears to have a raised oval shaped logo but lettering is not legible. Inside seems to be ok (for now) and has raised, molded lettering "PART 22510". If you don't have one but can tell me what the CAT p/n was (or is), or the Eisemann p/n was, or even another mfr cross-over number then that would be very helpful. Need for my very hard working R4 to keep it going.

Just bought that very same cap for $75. Try Kevin McWhorter at 309-303-2634. May not answer but he will return the call. Website is magneto-repair.com.
