A thai Dha ?

[Michel]

Can any Dha lover analyse the attached pictures and give an opinion?
I am totally incompetent in the Dha world, but think that this dha is from thailand,
blade is : 57 cm,
grip 31.cm,
blade thickness at the grip : 9.3mm,
width of the blade at its max: 26.6 mm.
Sheath in wood with very fine rattan binding.
Thanks for any information.
Regards
Michel

Shan, probably from northern Thailand.

Thank you Andrew and Mark.
XX century probably ?
I am hesitating if I should do anything on the blade or the sheath or just leave it as it is.
Thanks for your opinion.

Any time. :)

I think it is 20th C., though it looks fairly old, so perhaps the first half of the century. As for restoration, I would just clean off the active rust and oil or wax it. Originally it would not have had a high polish, though if you see evidence of lamination or edge hardening you might consider having one side poilished to reveal that.
