The Aeromarine-Klemm Corporation was formerly the Aeromarine Plane & Motor Co., and has been reconstituted and renamed to manufacture the German-designed Klemm low-wing monoplane.
This Klemm aircraft design originated in Germany in 1925. The type was successful and was built in many countries throughout the world. It was outstanding for its ease in handling and slow flight characteristics. The Klemm is of all wood construction and was designed to be disassembled in minutes. Klemms could often be seen being towed behind cars and stored in garages.
