Re: Sikorsky unknown helicopter

This design has some similarities to the S-51 (see the landing gear). That should indicate an 'S number' after or around S-51. I have no unknowns in my S listing after S-51 that would fit the bill. But, I have no details for the S-50 so may be (but a very very strong 'may be') we are looking at S-50.
On the other hand, my more realistic guess is that this is a design that never got to the drawing board and was, instead, restricted to an idea.

Amazing as it seems, this 14-passenger project found in the June 1944 edition of Popular Science not only used famed designer Raymond Loewy for its design, it was also found of interest by Greyhound Bus Lines, who are said to have "applied for permission to operate such craft on 49,130 miles of routes"!

Better quality from a press copy. The reverse side reads:
Greyhound "Air Bus",
Greyhound has made an application to the Civil Aeronautics Board for operation of helicopter service to supplement its nationwide bus system.
