National RFs Type PD-3 reduction drive with indicator provides a velvet smooth 6 to1 reduction that may be used to drive tuning capacitors or control potentiometers. The drive is of the planetary design, similar to those made by the Jackson Brothers. A clear acrylic indicator with an inscribed black line is mounted to the drive shaft, thus allowing the user to put a custom calibration scale behind the indicator. This drive is the same one used on National RFs Type NPD-3 Analog Display dial but offered at a substantial reduction in price. Only the drive and acrylic indicator are provided with this product.
