This is a repeater Altimeter sevoed from the Master unit. This one shows the altitude with a three-digit readout and an analogue dial showing 1000ft per revolution. The knurled Knob at the bottom left-hand corner is for setting the Barometric Pressure at the take-off point (QFE). The instrument may be based on a Kolsman design made under licence.
