[Gustav]

Could be a Pattani blade, judging from the shape of luk and especially last luk. Somewhere between a Carita and Malela blade.

Here a similar size of greneng (not so often (?) on a Peninsular blade);

and similar solution of gandhik/gonjo (possibly Terengganu).

Striking, how similar are some features of Peninsular keris sometimes to Bali/Lombok keris (this example of course beeing havily Bugis influenced), again Kembang Kacang/Gandhik/Gonjo area.
