There are some Thai guys really serious into vintage bikes here (Korat) , one with a collection of at least 30 that all run. I was at his place last week and he never mentioned it, I will ask him specifically as if anyone will know he will. He has everything from WLA's , Nortons, BSA's, Ariels, AJS's, and old BMW's, one real beauty from 1951. His name is "Kok" runs a battery shop.
