How late 15th to mid 16th century guns were aimed, in historic illustrations

Thank you, 'Nando,

I was aware of these and I am convinced that in Europe, too, sights were used from the point they arose (ca. 1460-70). The only remaining question is what their worth actually was, as the insides of the barrels were quite rough and not yet rifled.

Best,
