A very rare antique. High cockpit; look-down windows well back on side of cockpit; four-wheel fixed landing gear standard; row of cool-air intakes below cockpit windows; deep fuselage with peculiar bracing fillet marrying fuselage to tail boom.

This was the first commercial helicopter licensed in the United States. A few hundred civil and a few thousand military versions were built before 1955. It survived for years in the military of small South American countries, and may still be seen in utility roles in rural America.
