No problems, Shahrial. Glad to share these, and to help promote the ACM a bit.
Hi Detlef, these kerises are part of the permanent exhibits at the the Singapore Asian Civilisations Museum.

I encourage you to visit the museum if you are in Singapore. Put aside a full day for the museum! there are many other good artefacts on exhition, and they are well curated with proper write-ups explaining what you are seeing.
