Found out an interesting site for this subject..

for info, the C-33 is a militarized DC-2
the JRB a navy variant of the Beech C-45
Have not been able to find any kits of the Stinson O-49, the the North American O-47, and the SB2U Vindicator are. (MPM and Special Hobby, 1/72).. No B-12 kits either and I'm not sure how different it is from the B-10 (William Bros, 1/72). Don't know about the OA-9 Goose and the AT-12...
The O-47 is tempting me...
