EAA is in two weeks, I maybe able to get some real life pictures of some of this marking for you. They are expecting around 400 warbirds this year. I will see what else I have Clave.
Do you have a picture of the Ranger engined Texan? I have a postcard of this weird in-line engine version if you are interested in seeing. Let me know.
I have been digging at Wings Palette and Airliners.net so things are looking up slightly now
Revised list:
China - People's Republic
China - Republic/Taiwan
Guatemala
Haiti
Iran
Hong Kong
Laos
Morocco
Mozambique
Nicaragua
Philippines
Southern Rhodesia
Tunisia
I've seen profiles of this one where the purplish gray is a chocolate brown, but I like this version and am starting a model to be in these markings.....
