Detlef:
I agree that this one is not necessarily from the Indonesian Archipelago. HOWEVER, in Anthony Tirri's book,
Islamic Weapons: Maghrib to Moghul, there is a picture of the identical sword (but with a blue background) that he calls a
parang beng kok from Bali (see fig. 300B, p. 424). That sword is mentioned also in van Zonneveld's encyclopedic reference on Indonesian arms, although with a different hilt and the sharpened edge is on the S-shaped section (not the straight back). This example is based on Gardner (1936), and the information provided shows that is sharpened on the opposite edge to the one pictured in Tirri's book.
Based on the shape of the pommel alone, which is the initial subject of this thread, there is a passing similarity to a Tengerrese sword that was discussed here a few months ago (see:
http://www.vikingsword.com/vb/showthread.php?t=18718). The Tengerrese are from eastern Java. Interestingly, van Zonneveld describes a
ruding lengon (p. 115) from East Java as "an ancient weapon with a heavy, fancifully shaped blade which may be thick along the back, ending in a point curving forwards. The edge is extremely S-shaped." The drawing for this one is based also on an example shown in Gardner (1936) and appears closer to the subject of this thread than a
parang bengkok.
Despite the comments to date, I would not dismiss an Indonesian origin just yet based on the shape of the pommel alone. Let's see the rest of the actual sword first.
