Altimeter, Spain, late 1930's, Marconi Espanola, Askania, Fuerzas Aéreas de la República Española B-25 Radio Magnetic compassHere is an Altimeter, to 6,000 meters, made by Marconi Espanola under license from the German instrument manufacturer Askania. Very similar to the Askania FI22306 circa 1936. Based upon information from a warbird fan in Spain, it appears to have been used in the Hispano Aviation HA 1112 "Buchn" fighter used during the Spanish Civil War. See image of a Buchon panel in gallery.
