Charles, Interesting piece...the simple brass fittings remind me of of those I've seen on Burmese scabbards. The fitting on the handle reminds me of a Indonesian Kelwang, but that doesn't mean anything just a side comment. Love pieces with makers mark and your right you see this marking on a few different pieces...from different places...Northern Thai...Yunnan, Laos. The marking on the back of the elephant figure handle I think is a Yant/ Yantra:
