12 volt option

I thought I read somewhere that 12 volt was an option on m's. Did I dream that?

My 1950 M was 12 volt when I bought it. Delco # on the generator crosses to the same one on a 400. Were the diesels 12 volt on those? Only reason I ask is that it is all neatly done and the starter is a two bolt 12 volt. Most folks just kept the old starter is why I ask. Maybe someone had the old one wound for 12 volt? Seemed pretty professional for a farmer engineered job.
 
The farmer who really did a conversion right was a rare bird indeed :shock: :shock: ! But it did happen I'm sure :lol: :lol: . At least somewhere :? :? !

USA non diesel tractors that size didn't come with 12 volts until the 400 LP. During 1957 all 450 tractors got the 12 volts. MD used two 6 volt batteries with a 12 volt system. If the 50 M has a voltage regulator, a look alike generator and voltage regulator from the late fifties or early sixties along with a light bulb change was about all that was needed exept a resistor or coil made to use without a resistor. Starter could have work or be a regular M one. Also I have installed 12 volt starters from some later models on 2 bolt M drive housings.
 
Farmall 350 tractors except LP and diesel were factory 12 volt starting at serial # 13243. LP and diesel were 12 volt from the start. Also some 300 LP were 12 volt.
