In the late 40s, and while Franco ran things, the white rudder and black X were kept, the best I can remember. I have reached the age, where in my youth, I said I would never say, "I've forgotten more than you will know." The old grey heads would tell me that, but with my excellent recall, I thought it wouldn't happen to me, but on this forum I have found corrections to my memory. There is a reason pilots are put out to pasture by a certain age.
