Yes, the blade looks like from Madura Sumenep (the winged horse), and is probably recent. I saw some blades with similar decoration but covered with gold kinatah and not pierced through. The putut motif under the kembang kacang is an odd addition (not Madurese).
The warangka is in gayaman Solo style and the hilt in Ganesha style from Java North Coast (Tegal).
