This helicopter is the US Navy version of the Sikorsky H-19 Chickasaw.  It was a multi-purpose helicopter used by the United States Army and United States Air Force.  They briefly made an appearance in the Vietnam War, but were found to be severely under powered for the extreme hot environment in Vietnam.  This particular HO4S-1, bureau number 55-006, is historic as it was the first of ten of this model off the assembly line and was based at Whidbey Island NAS in Washington and in Alaska, most likely on Kodiak Island.  From there it was located in the Florence Air and Missile Museum in Florence, SC, which is now closed.  Then it was acquired by the Texas Air Museum, based in Rio Hondo, TX and later moved to Lubbock, TX.  It survived several hurricanes and severe storms while in Rio Hondo.  The magnesium alloy skin is battered, so the museum decided to leave the large dents in place to prevent more damage through much of the severely corroded skin.
