Looks like a complete TD124 MkII motor unit and armboard to me ... plinths are easily come by.
Be interesting to see what it goes for. TD124s are quite sought-after these days but we have no idea the condition of this one they can potentially have a lot of weaknesses - main bearing and the stepper pulley bearing and shaft can need attention, while the motors gum up over time (my motor was completely rebuilt by Martin Bastin and I've also have the stepper pulley bearing replaced by Loricraft) these are the sorts of things that can make a bargain purchase turn into a relatively expensive one.
