The original MC entry for Dragon of Tyr makes no mention of wings, and Baxa's illustration also shows no wings, but the beast does have a 45 Fly speed.
Dragon Kings says you get your wings at 29th level. The Dragon of Tyr is supposed to be 30th level.
Also, regarding the 'anti-dragon', or avangion (non-defiling version of the dragon), Dragon Kings said there had never been one, and then TSR goes and promptly invents one that had been around for quite some time in their second published adventure (Arcane Shadows), and invent another couple in the short stories. Still don't know if they annihilate each other on contact (like a xag-ya and xeg-yi), though.
