Right,we can ignore the tugh theory, should be lance heads but from where..I found two samples looking a bit similar here.
http://www.ashokaarts.com/non-edged/no-11.html . introduced as indonesian spears, but blades are not seen clear enough,and decoration style on silver collars..?? The question that must be asked can be ,if lance structures in Asian countries were differing very much or not from each other..I dont think they should differ as much as swords or daggers,but?? These pieces were brought here from Syria,that is the only certain fact about them.I made them resticked here. To Syria,could or why should indonesian spears had come in past?? I think I must examine Ottoman lances more carefully in my next visit to Military Museum..
