Thanks a lot for your efforts, Nik!
Even with a "don't touch" sign next to the pieces, I would not dare to exhibit crowded tables like this to the general public...
BTW, from your ample experience with local collectors, can you possibly comment on how acceptable surface rust is on such keris from a local POV? Some keris are apparently relatively well maintained with only limited rust dusted over the surface while others do show extensive crusts of active rust and probably extensive corrosion.
Regards,
Kai
