No, it was originally a CNC machine, and all the parts have Hurco tags. I
think something ran into it while it was warehoused. The fiberglass cover
over that motor looks different than all the rest of the paint. Like it was
newer or off a different machine or something. As far as encoders its not
uncommon for 20-30 year old plastic to fall apart. The encoder on the X
axis looked smashed. The one on the Y axis was intact, but crumbled when I
touched it. I was a little surprised that there was no encoder or even a
pigtail for one on the Z axis.

A mixture of coolant and way oils is pretty hard on most plastics.
There are some that
seem really resistant, like used by Fanuc, but many others do
deteriorate when exposed
to all that muck in the typical shop.
