The H-19 Chicksaw/Sikorksy S-55 was a very popular post WW2 helicopter, that served internationally. It was used with rotary piston and turbine engines, but was soon developed into the Sikorsky H-34 / S-58 / Wessex, which was produced in even greater number. The H-19 had a long military career in the late 20th century, and its unique bulbous nose, housing the original radial engine gave it a unique appearance.
