I recently acquired a Powermatic Millrite vertical mill (vintage 1976)
whose taper is a mystery to me.

According to ...

http://www.lathes.co.uk/millrite/

"The quill - which could be ordered with various internal tapers
including a Brown & Sharpe No. 9 (standard), B & S No. 10, R-8, 30
International and No. 2 or 3 Morse - was fitted with fine down feed as
standard with the option of a quick-action rack feed for drilling
purposes."

Well this Millrite is none of these.

It appears to be a Cat 30 taper that has been shrunk down...a "20"
perhaps? The bottom part of the holder has a triangular portion that
fits into the spindle where a nut then threads on.

Anyone have an idea what this might be?

Thanks

Hey TMT,

Got a picture. Your description reads like it might be an ER or
AutoLok style quick-change mounted on it already.

Take care.
