German LW Altitude Meter FL.22316-6

In a very good condition a hard to find German Luftwaffe Altitude Meter.This is an excellent specimen of the Contact Altimeter (Kontakt-Hohenmesser) Fl.22316-6 as used in the WWII-era JU-87 Stuka and JU-88 dive bombers and some ME 110 fighters of the German Luftwaffe.The white pointer indicates the aircraft altitude, from 0-6 Km, and the outer knob adjusts for barometric pressure.A very stunning not tested example!
