Ten and small 15 Bosch Mag applications

[Steve A]

I remember reading somewhere the late Tens and early small Fiftens used a Bosch Mag, I believe it was the MJB but not sure if thats it and the serial number range of use, I have a Bosch MJB, MJC and MRF I will get the MJB repaired if it is a correct mag, maybe the others will be a doner, they look similar.

TIA

Here is some application info:

The MJB American Bosch magnetos were used as replacements for the Eisemanns that came with the tractors from the factory. Two different mags were used on the Tens, the Eisemann G4 3rd edition and the Eisemann GV. The small 15s used the GV.
