Hi Mudi,
Greetings and welcome!
The ukiran is not original. The ukiran that came with the keris was East Javanese, but one with a dark band burnt round it with a hot solder.
The patra on that ukiran was not very nice, so I replaced it with this spare Solo ukiran I have (temporarily only). I'm just waiting for the right East Javanese ukiran to come along, but it would probably be a long wait because the peksi on this keris is very very long; all my other E. Javanese ukiran could not sit properly on the keris.
This keris is most probably not from Bali, because it is too small.
May I ask as to why we should refrain from sniffing at a keris Singa Barong? Or is that for kerises in general?
