Turkish Pala. Help with inscriptions.

[arsendaday]

Here is one of my recent buys.
Total length is 36" (straight line), the blade is 29" (straight line), the hilt 6.5" and the guard seems to be made of steel or iron. I think the guard and the hilt could be a recent restoration. There is also an inscription on the ridge of the blade. Please advice on the blade authenticity (makers mark? year?) and I would really appreciate any help with inscriptions.
