Krave Antiques has dated this piece to the 1900s.
The outer of the top half is covered in rich dark brown genuine leather, there is a sight level on both sides and the flask is a nice medium size so it slips into a pocket nicely, making it a wonderfully tactile and usable item.

The detachable cup has a gilded interior. The bayonet top cap seals well and does not leak.
Material: Solid Silver. Glass. Leather.
