This Huey was built as a UH-1D and TOC by the US Army in February 1967 but from August to October it underwent conversion to a UH-1H. From April 1968 until February 1971 it was stationed in Vietnam, after which it was on loan to the University of Michigan, flew as an air ambulance in West Germany and went on loan to NASA, flew as part of the Panama Canal protection force but by 1986 had been transferred to the Illinois ANG before retirement. It is pictured here as part of the Yankee Museum's Vietnam exhibit but was later restored to airworthy status and in September 2019 registered to Northwest Helicopters as N876GM. It was one of two Huey's that YAM traded in for a UH-1 66-1126/N240GH in airworthy condition.
