A small conical saddle flask with a silver plated bayonet or captured cap.
There is a defect in the shoulder of the glass, it is quite smooth on the outside, and doesn't seem to communicate with the inside surface.
The dark case closes with a tall lid with a billet fastening. The lid has a dent where it has pushed against the saddle flap over the years
The leather case is in good order.
Length (of case): 8¾" (22.5cm)
