This is an extremely rare WWII U.S. NAVY SACO (Sino-American Cooperative Association) River Unit 14 group named to Paul Ambrose West. SACO (Sino-American Cooperative Organization), was a U.S. Naval Group which operated during World War II behind Japanese lines in China.
This group includes an incredibly rare SACO "What The Hell" Pennant, original paperwork, photographs and bracelet.
This is the only original SACO "What The Hell" pennant that I have seen outside of a museum.
