リヒトホーフェン translates to "Richthofen" in English.
From the Ace of Aces Collector's Guide (http://maverick.brainiac.com/aoa/aoa3.html#20):
"A Handy Rotary Deluxe set in a slipcase was released in Japan. It was licensed to and published by Softbank. The slipcase cover art is the same as the boxed Deluxe Handy Rotary editions. Figure 32. The rulebook and illustrations appear to have been adapted from the Deluxe editions."
