Hi Dandi,
A supplement to Dom's reading:
Amal Mustafa Sahib Molla Emin (Amin) - Molla means religious scholar (usually in a small village / or a minor scholar in a city, speaking of course in 19th century context) I think the date is 1273 as Dom suggested it.
And yes, please I would like very much to see examples of famous Sliven (İslimiye in Ottoman Turkish) şişhanes.
Best,
