Built as B-25J-15-NC 44-29032, this Mitchell went into service with 18 Sqdn Netherlands East Indies AF (ML-KNIL) in September 1944 as N5-239 flying missions against Japanese installations and shipping in the SW Pacific. From 1946 until Indonesian independence in 1949, the NEIAF flew combat operations against the Indonesians, the B-25s being used in strafing and bombing roles. After independence, they were turned over to the new Indonesian AF (AURI), this one becoming M-439. The original 8-gun nose was changed for glass and it was initially displayed in camouflage with correct serial.
