Moro? Malay? Kris/Sundang

[Tatyana Dianova]

This is my first Kris. No scabbard, horn handle (most probably later, marked with B66 and anchor), but I loved the blade I am still not 100% sure if it has a separate Ganja or not. But the tang (rectangular) was definitely repaired. A thick and massive laminated blade. Ganja thickness (from top): 1.3 cm, blade length: 55 cm. Can somebody help with identification of origin and maybe age?
