Need advice on this keris I got from eBay

[Azman]

One the side with a clrearer Lam Alif and the tree trunk, I can see the pamor seems to be continuous and turns into island shape at the tip of the blade. Whilst on the other side it looks like an Arabic letter Ta as it seems to have like and inverted C with two distinct dots on the open crescent. One think interesting for sure is I could see the flow of the blade uniformly hammered grain boundaries running up to the tip. I thought this is very interesting and almost looks like a dissimilar metals being forged and pressed but I cannot say what they are. Some of the metallurgy looks shiny and some just plane white spot. Interesting point to ponder.
