According to Merc-O-Tronic Model 88 Magneto Analyzer Manual
page 31 Kiekhaefe-Mercury part # 396 – 650 Eisemann part # 24235
mfd rating is between .19 and .23
I checked Eisemann 72H Magneto and found Eisemann Part # 24235
stamped on base of condenser.
On line list shows Eisemann 62B and 72H use same Eisemann Part #
H24-235 = part # 24235. It may be possible to find good NOS or
good used condensers. A common magneto ,but, 1950 was 70 years
ago, so finding a good one may be a lot to hope for.
Now I need to build a condenser tester.
