All 16 inch telescopes had a Strain-Gauge motion control paddle. Tipping the front plate of the paddle in a desired travel direction, the paddle would give from a variable fine-drive motion to faster setting speeds. Simultaneously pushing down a control button on the back of the paddle, the telescope shifted into combinations of East-West Hour Angle and North-South Declination slew motion.
