Erik, i can't answer you question, but i did want to say that you seem to have a wonderful collection of figural hilts.
A old hilt like this, with the ogre-like qualities such as fangs and the crossed over arm posture of the Jawa Demam is indeed very interesting. What i am most curious about is if there is a specific meaning to this crossed over arm posture. Does it have a specific cultural significance? Likewise does the hands on knees posture also have cultural significance? Are the meanings here different or doesn't it matter?
