Ottoman banner spears?

[erlikhan]

I bought these two spear heads with the introduction as Ottoman banner stick heads, but I havent seen many exact Ottoman fighting spear or bannerheads till now so who knows? anyone here perhaps?
One's hilt bracelet is florally chiselled silver and other copper with silver edges. I wonder your comments about the interesting wavy structure of the steel layers.I hope you can see them in the picture.
