Altimeter (Contact), Luftwaffe, Fl.22317 JU-87 Stuka, JU-88, Kontakt-Hohenmesser H-21 vertical velocity/rate of climb indicatorsThis is a well worn example of the Contact Altimeter (Kontakt Hohenmesser) Fl. 22317 as used in the WWII era JU 87 Stuka and JU 88 dive bombers and some ME 110 fighters of the German Luftwaffe. See the illustration of the JU 87 blind flying panel showing the location of this altimeter. It is missing its center adjustment knob.
