while this says its for Nn3 or Nm the track gauge is 6.5 mm so also good for Z, this platform turntable requires only 1.5 volts to turn so a single AA battery will do the trick and a single toggle switch to control deck rotation and it moves slow enough so the operator can index it easily so they say.
