Thanks all.
Hank, I remember that discussion about Jeff's service and may contact him for some info. May or may not decide to send this off for bearings... these are in quite good condition, and the way the whole thing is designed tends to be protective of the open sides. I've also rebuilt a few 6A chucks over time, so hope/expect to be able to get this one back into good working condition... perhaps with the help of some parts from old ones that are stashed in a drawer.
Ag, the jacobs 33 taper is machined into the spindle, which is just one long piece of bar stock with splines on one end and the taper on the other. I can't tell/don't recall how that lower bearing retainer/threaded nut collar attaches to the spindle, but I believe it may be pinned through the little spanner nut holes. I have never removed that piece on any of these before, tho, so am not sure. But the spindle itself does have the machined taper. No morse to be found anywhere.

Is the Jacobs taper machined into the quill or is it removable? If removable, is it a Morse up yonder?
