Javanese or Balinese Nogo

[Karttikeya]

Yupe Jean, so many fake naga blades on the market nowadays, they could be recarved from old blade or aged by chemical to give archaic impression on blades, and this blade is no exception I also did not see different color tone as presence of core which was commonly found on old blade. But I've been curious about the wrongko origin, might it be East Java wrongko?
