Hullo everybody!

(again)
I don’t normally revisit a post unless it is to edit/add or I’m expecting a response. So, apologies for my late response.
Battara:
a. The sheath belongs to the siwaih. It wasn’t meant to be in the pix, but it was the closest thing to me to prop up the blades thus reducing shadow.
b. The cap on the top of the handle is Atjeh gold (18K).
c. Materials are: silver, suasa (<50% gold with copper alloy, mostly) and Atjeh gold.
d. As far as I’m concerned, the siwaih is from Gajo and the meuputjok from outside Atjeh.
kai:
- In answer to your first question, the meupoetjok: c.1755 (also see my reply to Battara). I am satisfied with their origins.
- I follow a particular Atjeh protocol whereby all such items come under one ‘umbrella’, reuntjong/rintjong:
reuntjong=particular term
rintjong=general term
rencong=Bahasa term
Best,
