More info about Atjeh weapons?

[asomotif]

will be getting within the next couple of months a once guilded silver rencong (see pictures below).

I have seen a rencong with traces of gold for sale some months ago in the Netherlands.
It was also a rather small rencong, same as this one.

Could they be of later date that the bigger examples that are often solid gold. and maybe more made for display / status. no longer a weapon ?
