Is this hilt a north coast Java? Ganesha, with a tumpal motif at the base, decorated with lozenges. Each lozenge quadrant having a 3 sided swastika creating a vegetative type pattern. Finally in the 2nd row down, right side photo, do I see eyes below the crook staring out? If so the two raised triangles give me the impression of stylized tusks.
Just my guess. I am interested to see at how accurate it was once others weigh in.
