Nobility Dha with Questions

[Battara]

Greetings folks,

Here is a dha I got from a friend. The hilt is carved ivory with a silver onion pommel and ferrule.

The blade appears to have some differential heat treatment.

Regarding the scabbard, it is wood covered with very thin silver with silver filigree.

I am thinking this is Burmese, but not sure if it is Shan or not.

Also, the carved figures on the ivory hilt - are they demons? What are they? (see last picture).

Finally, I am thinking this is late 19th century - what are your thoughts?

Thanks in advance.
