Alexish, i'm not sure that you really addressed Dr. David's questions other than acknowledging that this was a commissioned piece.
Was it commissioned by you personally for your own collection?
If so i am also curious to hear the answers to the questions that Dr. D asked. I am also curious why you would have commissioned the maker to add the unduk-unduk (seahorse) figures into the design since these are not really relevant to Madurese and Javanese style keris.
