Huhmmm I saw that same photo somewhere in one of my books, and the text on the photw said that the tail marks are nationalist but the roundels aren't repainted yet. in the photo the inner roundel seems to have different color than the outer (yes, I know is in B&W, I mean that the texture seems different)
Will look for that photo&text later, and post if if for one god-damned time I achieve to get my scanner working
