new member, old keris

[PeterP]

First of all, thanks for allowing me to join this forum. Let me introduce myself first. My name is Peter Paul, and live in Amsterdam, the Netherlands. I'm an art historian who turned away from art, and now work as a props manager for the dutch national opera. The props department i work for not only makes and buys the props for our productions, we also manage the weapons room. We ocasionally buy, make and modify weapons for the productions. As such, once in a while I come across a piece which we don't need for one of our opera's, but which i personally like, and buy it for myself. A few of these are kerisses, and I would like to post a few of these to learn more about them. I will post them in seperate threads so things won't get mixed up.
The first one I actually bought when I was still in my teens (way back in the early seventies), and this is also my favorite. I really like this one. Maybe because of the easy flow of the waves, or the beautifully rendered elephants head. Also the metal of this keris seems different from the other ones I have. It feels smoother, and has a soft shine which the other ones don't have, they feel courser and more prickly. Also the colour of the metal is different. It hasn't seen any arsenic and lime for ages, so it has a soft brownish patine, but through which the pamor is still visible.
Well,I'll post some images and hope some of the members could pass judgement on this keris, and I hope somebody can tell me more about it's origins, age perhaps ( although I know this is very difficult to judge from o picture), pamor type and more.
