Gentlemen,
After looking through the inscription, I've ruled out Arabic. I've attempted a reading but since the Arabic alphabet makes do with very little vowels, the actual pronunciation might be distorted. Hope someone with a knowledge of Turkish or Balkan languages can take it from here:
'Aqladan harsako yardawud foce Mustafa lataik sanat 1299'
At least we've identified the name Mustafa (who could either be the craftsman responsible or the owner) and the hegira year of 1299. Someone will have to check the corresponding gregorian year.
best wishes
