Are Asadollah cartouches/signatures found on Ottoman blades? Or only Persian blades?

[Jim McDougall]

Thank you for adding that old thread, its always good to see the 'good old days' years ago and the great writers who seldom appear these days.
Its good to see the Assad Allah signature (even though spurious) as opposed to the pictograph blades which I am more used to.

On the spurious use of renowned signatures and marks, this is not exclusive to any region or period, and was of course a common practice constantly with sword blades. Persian blades were much admired and desired throughout North India, Central Asia and Middle East.
Afghan arms makers were masterful at copying all elements of weapons and duplicating arms.

The copying of the sickle marks (Genoan and Styrian) on Indian blades seems most common on the paluoar, the Afghan version of Indian tulwar (Egerton 1885). The use of these sickle marks became popularly used outside North Italy (not just Genoa) via the prolific diffusion of trade blades to many foreign ports through the centuries.

Using that analogy, it is quite understandable that the Assad Allah signature would be copied widely as a mark of quality, but I cannot say which blade producers of shamshir blades outside Iran might have used them.
