Scott,
No photos I'm afraid. However, you might want to check out the book
Rhodesian Air Force: The Sanction Busters by Winston Brent.
Incidentally, the RhAF received 21 FTB.337Gs in 1976/1977. Some are still in service with the current Air Force of Zimbabwe. At least two former USAF O-2As were transferred to Zimbabwe during the mid-1990s. According to
http://www.scramble.nl/zw.htm, some FTB.337Gs and O-2As are currently operated by No. 4 Squadron from Gweru-Thornhill, while the National Parks Board are also said to operate O-2As.
Regards,
Jan
