Type M - Spindle Nose & Chuck

The Type M was not made with a threaded spindle. Instead, the spindle is hollow, with a tapered socket like an old style drill press. This example is fitted with a simple (but well decorated) two-jaw chuck that has extremely limited capacity. I have not yet tried to separate the male & female portions of this joint, so I cannot say if this is the elusive No.0 Morse taper or not.
