Starter Motor question

[Captain John]

My 42 GPW is motor pool and fitted with an MB engine . The jeep had been converted to 12 volts and a alternator fitted . The starter motor is an Autolite with the brush cover band marked MZ 4113 the starter body on the thinner bit is stamped PS 79 A . Is this a WW2 6 volt starter or a later CJ unit which could be 12 volts ??? . Also does the armature have a front and back bush or only a back one the front being taken care of by the bell housing bush ??? .

Thank you , Captain John in warm spring, rain on the way, Suffolk County England .

That is the correct housing number (PS 79 A) and band for a WWII starter.
It has two bushings.
Unless someone has tried to convert it to 12 volt...it is still a six volt unless this is a franken-starter made up of different components.

If you bench test it with a 6-volt battery and she cranks over then it is probably still a 6-volt starter....but if you try a 12-volt battery she should REALLY spin!

I don't believe a 12-volt starter will do much when hooked up to a 6-volt battery though.

It is normal for this starter to have bushes in the rear & front end plates + one in the bellhousing.
So the armature is supported in 3 places.
Don't worry about 6 or 12V the starter will run satisfactorily on both but don't overdo it either way.
