I got mine
from Amazon (was only $17 then!), but they are also available on eBay: nothing special about them. I modified the mounting on the mill, added a bolt circle & cover plate to the hand wheel hub and changed the skinny knob to the egg-shaped one.

Drilled the hand wheel hub & mount (between the hub and fixture plate) and tapped the holes in the mount in one set-up (made it easier the hold the hand wheel and insured that everything lined up). I purchased a
replacement mount from LMS (they call it a "pivot") so I could use the mill to make the modifications.
