From The Spangenberg Index,

could be the US Navy was responsible about that contest,it was about Rescue and Utility Helicopter,and the
tenders were;

- United Helicopters (Hiller) L-3
- Kellett
- Higgins H-3
- McDonnell H-3
- Fleetwing Model-52
- Sikorsky

For McDonnell,it was Model-42,about Sikorsky,definitely it was in DS series,and may the Hiller
proposal was developed from this one.
