Look at the USMTA website. There was a teacher in New York that teaches muay boran and he is recognized by the World Muay Thai Council. Most other schools are in Europe. Kru Marco DeCesaris wrote a book on muay boran and if i read it right muay boran was the name given to the older styles (muay korat, muay ta sao, muay chaiya, muay lopburi) around 1996 to try to keep them around because all the old masters were dying and know one was continuing the old styles. Panya Kraitus who wrote Muay Thai: The Textbook of Pahiyuth, is a student of a late muay chaiya master and his book is considered to be the bible of muay thai. Check it out if you don't have any luck with muay boran.
Marco de cesaris is not a real master of Muay Boran but is a good buisness man!
