This is a priming powder flask used for muzzle loading flintlock firearms. It was likely made in the Ottoman Empire or Persia during the 18th or 19th Century. The body is constructed from solid brass and features extensive hand engraved patterns including floral and geometric designs.

The device uses a spring loaded lever mechanism to control the flow of powder. When the lever is pressed it opens the spout to release a measured dose of fine priming powder directly into the flash pan. The flask has a curved shape that fits comfortably in the hand.

It measures approximately 14 centimeters long as seen in the photos. There is a small metal ring at the base for hanging it from a belt or pouch. The surface shows an original aged patina and wear that confirms its historical authenticity. This piece was an essential accessory for a soldier or hunter using black powder weapons.
