stepper motor with threaded rod thru rotor

   Those were the drive mechanism of some 8" floppy
drives.  They're now rare items.

Yup, that's the downside of purchasing surplus and/or remaindered items.
Eventually, they go away. If the steppers you're referring to were part
of a surplus tape head positioner assembly at All Electronics, I picked
up a couple, myself. Good price for some miscellaneous fasteners,
springs, and a groovy stepper motor and lead-screw combination (sorry
for the lame pun).

It looks like

is *possibly* a similar actuator.
