Hello Ian. Lovely piece. You can definitely see the Tai and Chinese influences. The makers mark and written characters are both identifying. It says HuSa in Chinese so the blade is made by the Achang, a Tai minority in Yunnan. Known for their blade quality, blades were traded throughout the region with other Tai groups...so it is not uncommon to find them with different fittings like you see here. Neat piece Thanks for sharing
