Old keris ?

[Richard G]

Thank you Henk, Rick and Alan,
No, Unfortunately there is no mendak. I have already given the blade a preliminary clean by soaking with Plusgas and rubbing down with crumpled aluminium foil. this has got rid of most of the surface rust but it is still present in the "pittings" which gives the blade a brownish tinge. I will try vinegar, lemon juice etc. and see what happens.
I also attach photo's showing the scabbard. I am not sure whether or not this is original, it is a very close fit but not perfect. And another showing some of the pitting on the blade.
Any idea as to age or origin?
Regards
Richard.
