Delivered to the USAAF in July 1940 as 39-51. Became NX61Y in Apr 1945 and served with the Great Lakes Carbon Corp. (GLC) from Aug 1950 until Jan 1953. Later to N34C, N534C, N230SU and N534J. Traded with the USAF Museum in May 1971 and loaned to the Pima mueum in 1973. Originally displayed in its faded last civil livery as N534J, but fully restored in the nice Great Lakes Carbon Corp. colours in 2007 and rolled-out as such on 15 Aug 2007. Note the small GLC logo on the tail, which was carried by all GLC aircraft.

This is a very rare aircraft and is very well preserved at the Pima Air Museum.

Restored and displayed at the Pima Air and Space Museum, in the markings of the Great Lakes Carbon Corp.

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.

Delivered to th USAAF as 39-51 it carried the registration N61Y early in its civilian career in the late 1940s and into the 1950s. Has the small "GLC" logo on the tail.
