Nice score. Blade certainly looks ginunting-like based on classifications I have learned here. Is it chisel ground? The guard style is not typical for these nor the pins securing the handle but the scabbard, ferrule and dragon would align with that classification. Kino posted an unusual old dragon handled ginunting-like sword with atypical guard. We have also seen some Visayan daggers with similar guard style. They would be more typical of Luzon.
