No, only the very early ML10 had plain bearings, later ones went on to standard bearings with a limit of 1450 revs and then the Speed 10 came out but the headstock was the same as the middle model. Why the difference between 1450 and 2,000 was never made clear other than pulley ratios.

Conect bought a complete ML10 and converted it, they wanted to buy a stripped down lathe from Myford but Myford would not sell them one so they threw away many parts and put their own on.
I do have books on the lathe and mill but can't lay my hands on them at the moment, I will look later.
