This is a stretch (remember, I don't read Thai), but if you get no input from anyone else, try this. In my Thai book, this medal appears in what you might infer would be the 3rd senior position. Without scanning the page, I'll illustrate it thusly: 1 2 3 (your medal) 4 5 6 On the other hand, the caption on the left side of the page (Imagine that this is in Thai) says ckklsoguwehbh % 6. An extremely fertile imagination might think that this suggests Class 6. This discussion is surely outrageous enough that it will provoke someone to do proper research and come up with the real answer, and we'll all have a good laugh. (And where are you getting all these Thai medals, anyway?) Hugh
