These are definitely swindicators (switches/indicators) from a DEC RL01
or RL02 drive.  You can see the unit select number has been "obscured"
in some way (white paint?) on the "READY" switch.

Wonder if they are using just the switch assemblies, or perhaps using
the big voicecoil positioner of the RL01/RL02 as part of the system that
magnetizes the ferrite?
