Originally built as a UH-1D-BF, taken up by the Army in November 1967. Served in Vietnam from March 1969 to March 1971, almost entirely with Company B, 227th Assault Helicopter Battalion (whose marking is on the port cabin door), 1st Cavalry Division, (the latter's marking worn on her tail). The display sign calls our attention to "numerous bullet holes," which attest to her combat service.
