http://www.kitwoodhillmodels.com/brands/Nn3-{47}-Nm.html 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 cpmtrol deck rotation and it moves slow enough so the operator can index it easily so they say.
