I think,
Megantara not just has 7 luks. It can be 5 or 9. The Ensiklopedia just give a one (Luk 7) of several kind Luks of keris with dapur Megantara.
Dapur of javanese keris not too exactly same with shown at Ensiklopedia Keris. Perhaps, many dapur of Javanese keris can't be identified till now.
Or..., some of piece looks like different, but it appear a same dapur.
For example, Keris with dapur Panji Pengantin (Ensiklopedia Keris p:348), try to looking at appendix which shown a Panji Pengantin keris, but it has a different Kembang Kacang
Btw, would you please post some close up photos at sorsoran and bottop of gonjo, so that we can look with clear at "C" (Jawa : Kruwingan) at Gandik ?
regards,
Mans.
