Mataram Wedung

[A. G. Maisey]

I'd give both as Surakarta, and both as 19th century.

Athanase, if this wedung was mine I'd be using cold gun blue on it. Repeated applications will give a very deep blue, approaching black. It is even possible that there might be a metal treatment that will blacken it. Try sculptors supplies for a black treatment, and gun shops for the cold blue.
