Found this this is new one for me.

The ultimate evolution of theDelMar helicopters was the tandem-rotor DH-20. Conceived as a super-portable medical evacuation helicopter, the DH-20 was powered by twin turbine engines and designed to carry a pilot and two passengers, or a pilot and one passenger in a litter. Remarkably, the entire helicopter was able to fold up for ground, sea or air transport, and was capable of operating in and out of far smaller landing zones than a traditional helicopter. As testing of the DH-20 continued, however, the requirement for such missions declined, and the aircraft was never put into production or flown operationally.

Soem pictures of the DH-1 "Whirlymite" from "der Flieger", Januray 1963. The drawing
