Thank you for your comments!
@Detlef
Thank you very much for the link! The discussion there was very useful for better understanding my Kris.
@Marcokeris
Thanks!
@ Willem
Taking more close-up photos would require some natural light and mounting my gear on a fixed stand, and considering that I usually arrive home from work rather late and that Saturday I will go on holidays, I'm too lazy to make all the effort. The opening in the Wrankgka and the silver fitting are flush on the interior as well so I am prety sure it is the original wrangka belonging to the blade.
@ Jean
I also think the silverwork may be latter addition. However, I think it is of the correct type and style.
@ Roland
Thank you, but I agree with Alan (see his comment below). The pamor is quite visible and I like the lesser contrast.
@ Alan
Thank you for your suggestion! I was thinking the same.
