Could this be a French-inflicted unit abbreviation? :-)
Mille in Fracais is 1000.

       Didn't see this when I posted, I was referring to      the same thing.

When looking at            schematics from the 1930s and even into the 1940s, for some            reason, where the values of especially resistors are            concerned, a number of manufacturers used an "m" instead of            a "k" to indicate a multiplier of 1000.
        

          
        

          
        

          
        
The first time this            happened to me, I started scratching my head trying to            figure out why all the very high value resistors.  Then, I            realized that the "m" was used instead of a "k".
