Indeed it is a Balinese Wedung. See Zonneveld pages 152 & 153.
A good solid piece with black palm woon handle. The steel in these Bali knives and the Kudi Tranchangs is awesome hard and sharp iron, the edges and hardness have always impressed me.
I believe the dragon to be Naga Banda, see the image attached below that I presented here;

The protrusion to the top was noted by a friend viewing the forum as looking like the beak or Garuda, when viewing the second image from a play viewed in Bali, I tend to agree as the Naga Banda and Garuda were carried on their own floats during the funeral ceremony.
