Delivered to the USAAF as 39-51 in 1940. Sold as NC61Y after 1945. Reregistered as N61Y after 1948, N34C in 1953, N534C by 1964, N230SU in 1966 then N534J in 1968. To the museum in 1975. Restoration and repaint in Great Lakes Carbon colours as N61Y completed in 2007.

Built for USAAF as B-23 39-51 but operated as a transport aircraft without redesignation to UC-67. Disposed in 1945 and served several corporate operators until 1973 when acquired by the Pima Museum. Seen in course of refurbishment for continued display. Appears to be painted as "N5340", but that is merely a combination of previous registrations N534C (carried in the mid 1960s) and N534J (carried since 1968).

Prior to restoration. Seemingly marked as 'N5340', due to previous registration N534C showing through.
