The Title is "Sikorsky Helicopter Flight Theory For Pilots And Mechanics". I highly recommend it for use by those wishing to learn more about the subject as it is written in a manner that even Pilots can understand and has drawings for the CFS CFI's to color with wax crayons.
In my quest to find one....I discovered there are three printings of that fine tome on helicopter aerodynamics.....1953, 1964 (the version I carried for years in my helmet bag) and 1994 (which according to John Dixson has a gray cover).
I have found a few at some used book sites.
They are not cheap as they are scarce.
Thank you for the recommendation, I just managed to grab a decent '64 version off Amazon.
