Hi Maurice,
Nice rentjong with a nice provenance.
Lucky Danny that he went there and was able to purchase the 2 lances.
Your rentjong has a interesting scabbard which is very rounded on the bottom.
I owned a similar one years ago which is depicted in Jean Greffioz' book The Kris.
Love to see better pictures after cleaning.
Especially of the scabbard and it's carvings.
Best regards,
Willem
