Thank you very much Nathaniel.
This being written in the Thai language would indicate it may be a Thai court sword, unless they use the same written language in Laos. Excuse my ignorance in these matters.
I did a quick search on google to no avail, have you or do you know of this store in Thailand, is it still existing or closed down many years ago.
Any help you or other members may be able to provide will be highly appreciated.
Thank you,
Erik
