Agree with David, the blade seems to my eyes antique. And I don't think it's Tilam Upih but I am unsure, I would need to see other pictures.  
The sarung seems to be without patina, could be refurbished or recent and is a somewhat special Jogya gayaman form. And yes, please rotate the hilt by 180 degrees.
