I was very happy to acquire this matching pair, which I believe to be dated to the first half of the 20th century. They're really small - the keris is 13 inches overall, 9.3 inch blade; the badek is 8.6 inches overall, 5.5 inch blade. Small guys, but they cost me nearly an arm and a leg.
They're just perfect for wearing, which is what I would do for the coming Muharram.
