A sterling silver travel drinking flask with large removable drinking cup.  This is a stunning piece, very simple in design, however, what makes this flask unusual is the large, thick gauge, removable drinking cup that slides off the main body of the flask itself.  A very unusual feature to the cup is a small, concealed, hinged compartment that sits at the base of the cup.

This cup also doubles as an added layer of protection to the flask, to prevent any damage to the precious cargo. There is a slight curve to the back side of the piece in order to fit more comfortably in a breast pocket.

Hidden compartments like this are very unusual on drinking flasks, and as such it has a registration number on it.  These usually signify a more unusual and special piece, or something of exceptional quality.  It is hard to fully know its intended purpose, but being that there is no striking plate, it is unlikely to be a match safe, or vesta.  Therefore, it would have been for either snuff, or a small amount of tobacco.

The flask has full assay hallmarks on both the flask and cup having been made in Chester, England, in 1899 by the small, but well regarded silversmith's Edward Osborn Marples.  The lid is a classic bayonet style fitting, secure, and with a cork liner to prevent any leakage.  The piece is in excellent condition  throughout and ready to be once again put to use.
