Hello,
There are many possibilities but based upon what I can see I'm in the opinion that your keris has been repaired/altered--or even made to look unusual from day one, I'll call it dapur kreasi baru/owah-owahan or the like --contemporary/non standard dapur (might be once sepang-urubung damar combo which is okay, anything in that direction), tangguh kamardikan--modern/vintage, pamor wos wutah, origin Java-Madura somewhere, I don't have any opinion on tuah/isi. I could be wrong. Nice material but rather lacking on garap I would say, sorry. I wish better condition keris coming your way soon
