Steel designation

[metalonis]

We are being asked to supplied a machined part with a material specification of MO1 (or maybe M01?) tool steel. We are familiar with M1 and O1 steels but, not MO1. Any ideas if MO1 is (or was) a legitimate designation?

Maybe its a typo and should read 'M10'?

or did they put in "zero one" because they thought that it should be a two digit number.
