Powder Chest

Three identical rectangular brass powder boxes of different heights. Each has two eyes in opposite corners on top and a locking mechanism. The locks are of different types. The smallest box has a double lock marked 1, the outer lid hinged and secured with a large screw; the inner rim is lined with an unknown plastic. The inner lid is loose and has a ring on top. The largest box has a single lid marked 2, of the same type as the outer lid of the smallest box, also lined with plastic. The medium-sized box has a double lock marked 3; the outer lid features a bayonet catch and a hinge allowing it to rotate; the inner lid is identical to that of the smallest box.
