Me too, have a feeling of Thai rather than Burmese origin. There 's no photo for tip detail. But "Hua Bua" (lotus tip) or "Hua LukKai" (chicken tip) tip profile usually associated with central Thailand origin. The handle/blade ratio also fit average value of Thai's. The handle seems to be made of giant rattan. Some parts were missing. If you can take the handle off and take some pictures of the tang, tang thickness might help for its age ID.
