Vintage WWII Aviation Globe

Vintage WWII Aviation Globe that offers planned & existing flight routes circa 1942, in addition to a time measurement guide on the horizon ring to calculate flight time of a route (based on an airplane speed of 300mph). From my research, the base material is made out of pressed cardboard, as metal was needed for war efforts and therefore scarce. The orb is of pasteboard, representing a map circa 1940, including existing & suggested aviation routes. The sphere is removable from the cradle-style base. It DOES NOT spin, so you would have to lift it off the base to move it around. The horizon ring on the base identifies miles, hours of flight time, info on the wind system in addition to atmosphere, the earth, and great circles. Base has a "wood grain" finished print. Includes a scale for great circle distance and flying time that rest at the top of the globe. Also at the top of the globe is a dial that has sunrise, sunset, and midnight times. The age of this piece is based on political borders displayed: - Germany has expanded in Europe, annexed Austria, & occupied former Czechoslovakia - Italian East Africa is no longer visible - Israel is not on the map yet - Manchuria in China is occupied by Japan & re-named Manchukuo Height of Globe on Base w/Scale on top is about 13.5" tall. Some condition detail can be seen in photos. Please message for more details.
