I don't recognize the name of the pamor but attached is what Ensiklopedi Keris described about Benang Saukel, perhaps other members willing to help with appropriate translation.
Dapur might be Kala Dete/Deteng/Dite (as described by Ensiklopedi Keris)-- among other details: straight keris, with kembang kacang, lambe gajah and greneng. You might want to get this book if you want to name pamor, dapur, tuah, tangguh, etc in regular basis (in Bahasa Indonesia only as far as I know).
Nice mendak, is it silver? If so, a silver Jogja pendok will be suitable (but I don't know, blade condition appear too poor to go to that direction--at least from my point of view). Hilt appear to be good quality. Warangka iras is priced more than the one with separate gandar. Age of a keris is another difficult matter, perhaps late 20 c.? Any provenance? Please consider to collect keris with better blade condition as I seems to remember being told that owning (read: collecting) broken keris bring you bad luck
