Roland, just to confirm:- the keris shown in post 142 is your keris, and it is attributed to pre-1900?
Alan, yes this is my Keris and the description of the auction house was 1800 or earlier. If you could see the scabbard, you would see, that this Keris is older than 30- 50 years or so. Detlef (sajen) saw this Keris many times and he also said ~1900.
