Some additional pictures - is the ganja separate, or iras?
Definitely separate, Shayde!
Keris Kebo Kanthong Luk Lima seems to be a good description for this rare dhapur.
Looks like a good blade. Could you please take pics of the whole blade (as well as a close-up of the section with luk) directly from above (vertically), i.e. not at an angle? Thanks!
