Altimeter (Contact), Luftwaffe, Fl.22317 JU-87 Stuka, JU-88, Kontakt-Hohenmesser P-47 This tachometer received electrical signal

This tachometer received electrical signal from a generator located proximal to the engine drive to indicate engine speed

with the mast protruding upright externally

after being deflected

but doesn't affect the cosmetic appearance and could be replaced

in an audio frequency signal the average frequency of which is proportional to the altitude of the aircraft above the ground
