So there you go David! There is your answer...they are not sure who gentleman is with the keris in his belt for certain...just academic and non academic speculation...my opinion is it's just basic artistic license but it shows at least ethnic groups the artist knew, however the details are construed...which is very common with artist renditions anyways...but the period of the cabinet is at least known

It was fun researching it! Always thrilling when you find the answer!
