This powder box was used to put powder in the powder-pan (very small bowl) at the end of the barrel next to a tiny hole going inwards to the powder and the bullet. The powder in the pan is lighted by the fuse and subsequently the gun fires. The weights is 300 grams and 21 cm in size.
When the musket was no longer used (around 1880) boys would wear it as an amulet on their back. Ref 2 Stuhlmann 1910 page 127 also refers to the filigree silver work on the khanjars, curved silver powder horns and silver tubes in bandoleers that used were widely used in the past by the irregular soldiers of the Sultan.
