Not really sure what you're trying to tell.
The keris posted above is not a madura keris. The keris is left in its original style "as found". Pendok has nice detailed silverworks (feel free to call it Banyumasan, but I wouldnt). As mentioned the hilt has probably been added more recently (who knows maybe in Solo

. So what do you mean with "adjust the keris" ?
The link you provided is a discussion about a madura keris recently sold on eBay, or more specific "if that was a catch or not". I really dont see the relevance of that for this item, unless you mean that it also could be a catch. In which case I would agree.
If you need more detailed pictures of the pendok let me know
