This is actually Harvard II, RCAF s/n 2951. It was struck off charge in December 1946. Registered with the FAA as N99839, it was operated by Avery Aviation and Hawkins & Powers, both companies based at Greybull, WY. Acquired by the USAF Museum, it was loaned to the Castle Air Museum in the early 1980s.

ex N99839

Despite its markings here, this Harvard never saw service with the US military. It is ex RCAF 2951, which was taken on charge on 11 March 1941 and struck off charge on 11 December 1946. After many years of storage it spent some years in a museum in Ontario in the mid 1970s. It very briefly became C-GDJC in Dec 1975 before sale to Hawkins & Powers Aviation in March 1976 as N99839. The Harvard finally arrived at the museum here in the early 1980s. Its identity is also quoted as ex RCAF 2684 c/n 66-2417, but in 1976 N99839 was definitely officially registered as c/n "66-2684".
