Murad, son of Abdullah
Gun maker active in 1524. The inscription reads "Turkish gun made by Murad, son of Abdullah, Chief Gunner in 1524" but that doesn't make it clear who was the Chief Gunner: Murad or Abdullah. We guess the information is inscribed on the gun somewhere (else how would it be known?) and perhaps it is equally ambiguous there. And perhaps that is all that is know abut Murad - we certainly can find no further information on the web about him.
