"A Passion for Indian Arms" Book Review

[Kubur]

Talismanic inscriptions and decorations are very well known (blessing and protection)
In the case presented I do not believe in old rivet holes.
There is another option already mentionned above:

proof marks or factory/quality marks.

You have some brass or even gold fillings on Ottoman blades.
They are always connected to a workshop and demonstrate the skill of the smith and the quality of the blade.

Some of these marks including stamps became talismanic with time.
I think at the gurda marks for example.

Happy new year
