This form of sword from Sumatra, Indonesia is known as Pedang I. It has a clear influence from the Indian subcontinent and usually employs a foreign blade, as most probably the case here: A saber blade, probably a European trade blade, 30 inches long . Steel basket hilt with down pointing langets and a pommel spike. All very nicely engraved. Total length 35 inches. Good condition. Blackened areas and patches of pitted spots. No scabbard.
