Hi lelang69,
I do not know much about keris, but here goes...
The sheath is a Surakarta styled
Ladrang form. It's definitely not
gayaman/ganyaman. The
wrangka is
gandar iras, as mentioned by David.
(There seems to be a large split/crack/break along the vertical line of the wood grain, I guess). The oversheath (
pendok) is
pendok blewah. The hilt (
ukiran/jejer), is in the Surakarta
Yudowinatan form (as mentioned). The hilt ring (
mendak), is a bit too small and not of known Solo/Surakarta form. The blade's
luk form is fashioned in the style of
luk Kemba (gentle waves). The blade tip (
panetes), is
nyujen (narrow tapered point). I hope it helps.
The blade and pamor looks nice.
I'll leave it to the more knowlegeable members to comment.
The pictures are blur, dark and small. The angle of which it were taken doesn't help either.
