ID on silver-mounted swords with serrated blades.
 

These are out of my comfort zone.
The mounts are sterling silver. What is the exact attribution?
Thanks!

Unusual!

The silverwork images look Burmese or Thai.

Yes, I thought Burma as well, when I saw the hilts, however I don't recall the Burmese blades of this shape (to me they almost look like some type of Indian temple sword blades), which imho may indicate that these were some type of ritual swords?

What is the thickness and bevel on the blades? They look rather thin.

THEY ARE LIKELY PROCESSIONAL SWORDS TO BE CARRIED IN ADVANCE OF ANY ROYALTY IN PROCESSIONS AND SUCH. THEY ARE ALSO SOMETIMES REFERRED TO AS BEARING SWORDS. THEY ARE USUALLY VERY LARGE AND HEAVY WITH POOR BALANCE AND NOT MUCH OF AN EDGE ON THE BLADES.
I AGREE THESE ARE LIKELY FROM THE THAI/BURMA AREA.

I think I recall that there is a type of Burmese tribal Dancing Dha listed in Rawlsons Indian Arms,that has some shape similarities. {differences as well.}

I haven't got mine to hand but if so it might suggest Burma more than Thailand?

Are the grips really bending in opposite directions, or am I misreading the photo?
Regardless, quite nice looking pieces!
