"Sunny Side Special"
This is a photo I found on EBAY. It has a few unusual things about it. The serial number is a Chinese designation that also supports why no USA roundels anymore. Also the antennas on the underside of the aircraft are very unusually placed. Possibly a special arrangement for an armed aircraft that had a radio purpose while in mission?
This aircraft is most likely a 1st Bomb Group CACW B-25H.
Outside chance it is a 21st Recon squadron who also used B-25's.
