We can assume also that a lot of matchlocks have been turn into flintlocks...

Kuber, the same could be said for Indian matchlocks as well but somehow many of those have survived, there has to be a better reason why so few Ottoman matchlocks are still around.

Here is some interesting information on the influence of the Ottomans on Indian firearms, it is surprising that the Indian matchlock does not look more like the Ottoman version. I do know of one matchlock that is supposed to be Indian but has an distinctly Ottoman look.

Indian matchlock gun, probably late 18 to early 19 C. 47 inch barrel forged from fine twisted steel (Damascus), with a makers mark and decorated with gold inlay work (worn). Wood stock mounted with steel plates, decorated with ivory inserts and ivory butt . Chiseled muzzle, barrel is reinforced to the stock with bands of leather strips (added later), length 62 inches. The barrel looks older than the stock, probably a secondary use for it, the stock is repaired at the tip.
