Hello 'Dil52',although I don't have the MAAM-SIM DC-3/C-47, I think I can help you to answer your question.I think you have just the proper version of the MAAM-SIM (at least what I can read from your post). The Douglas DC-3 has many 'names' such as Douglas DST, DC-3, DC-3A, R4D-6, C-47, Dakota and many many more.Look here to see some of the names of the DC-3. You can also look on this page for more info about the DC-3.Klaus
