Good questions...
1)WN7/WN7A Flywheel and magneto plate should be F 514S
2)Magneto plate is machined to match curve of core when fastened in position
Even so like cores should be good enough matchup given that core
likely were made to a uniform standard. A serious mismatch of coil core
and magneto plate probably due to an unlike core swap.
Phelon used a common pool of components to make a range of magnetos
in same or similar model line. The die cast plate and the coil cores
have a unit part number so no part number for core.
Measure diameter of die cast plate across the opposite coil machined
surfaces an I may be able to match up cores that will fit. Worth a try
and may reduce clutter on bench. Cut and try engineering not blind
parts swap.

F514 series Magnetos started with A and went thru Z Lots of commonality
but 514A used on KF5 series and 514C used on KE4/Mark7 are not same diameter
even though they have many components in common. Phelon was willing to do
as Mercury desired. Mr. Kiekhaefer's background was in practical electrical
engineering so he knew magnetos. He also had gotten an early lesson in tricky nature of magneto suppliers.
Almost have the powermatic back together. Determined that it will fire over and run with the coils/laminations that is has now. Now I need to find a Mercury/Wizard female fuel line connector that fits on the engine-end of the motor. Any ideas what size this is, or a source? Thanks.
Well, I put the 55 Wizard WN7 Powermatic 12 in the test barrel today after securing a female fuel fitting on Flebay. It dripped a little gas...very slowly, so I need to revisit the carb float, but it came to life on the fourth pull and ran pretty well in N. I went a little heavy on the fuel/oil mix, 16:1 instead of 24:1 because I wasn't sure and it smoked heavily when I got on the throttle. Was able to smooth it out by slight tweaking of the high and low speed jets, but it wants to die when I drop it in gear with the throttle down in the shift range. Not always, but guess I still have some tuning to do. Is it all right to run this gem at 24:1? And is there a common cause for dogging when it drops into gear? Thanks in advance for any input and for your help in getting this far with it. :)
