Back when I was servicing IBM typewriters, the guys in the shop would play a game. Pull out of seldom used part or tool and see who knew what it was.
I was cleaning out a box that came with my lathe/mill and found this. Appears to be a collet of some sort. But smaller than anything I've ever seen.
It has an internal thread on the backside. Maybe 5/16-24.
Name that part

Re: Name that part
100% a Morse Taper collet, this chart will tell you which one https://uwoodcraft.com/morse-taper-dimensions/ but there's other and better web sites. That chart also isn't complete since there's at least a MT 0 and a stub length MT 4 1/2. Shereline lathes for example use a MT 0 and quite a few lathes for some reason used the MT 4 1/2 in there head stocks.

Re: Name that part
Looks like a collet for Bridgeport M head or a little clausing milling machine
Re: Name that part
Yep, looks like a Morse Taper milling collet. Probably a #2 which would probably have a 3/8-24 thread for a drawbar, though there doesn't seem to be any standard.
Here is a #2 1/4" from LMS with a 3/8-16 drawbar thread:
