Matchlock gun of Afghanistan?

[ariel]

That's the rub....

Barrels were imported and transported, and the attribution of the finished product ( the gun in toto) is often determined by its stock/butt.
The Corrado's gun is not of a classical Afghani or Sindhi fashion.
On the other hand, here is one from Ashoka Art gallery, defined as South Indian. Its stock looks more like Corrado's. And yet another one from the same collection, also attributed to South India, and even with a rattan binding.
Rickystl and Fernando: thanks for your input, it provides quite a lot of food for thought.
