hi willem,
there's going to be an auction at hessink's with several sikim and rentjong without scabbards, perhaps you can cut one down yourself (of course this is a joke...) also some nice european weapons. the indonesian stuff is not very spectacular, only two or three nicer swords. parang latok without scabbard and a sikim with ivory sheathmouth.
