This Thai AF UH-19D Chickasaw is displayed in the Royal That AF Museum at Don Muang, Bangkok. H.3-3/97 6313 is c/n 55757. Not sure if it has any history with the US prior to moving to Thailand.

Note that this 1954 model S-55 does not have the 'angled down' tailboom fitted to most US models, to avoid tailboom rotor strikes- in this pic you can actually see how close the main rotor can get to the boom.
