Vintage English glass (hunting/travel) flask in leather travel case, ca. 1930's

Rare vintage glass  whisky flask with glass stopper, silver coloured metal screw top and drinking cup in brown stitched leather travel case with shoulder strap.

Leather casing measures approx. 20 cm x 7 cm x 5 cm (7.8" x 2.75" x 2 ")
Shoulder strap is adjustable.
Glass flask measures approx.  18.5 cm x 6.5 cm x 4.5 cm (7.1"x 2.5"x 1.75")
Flask fits snugly in the leather casing.
Total weight (before packaging) is approx. 700 grams

Both flask and leather casing are in good vintage condition. The drinking cup still has it's gilded interior. There are some minor signs of use and the leather casing has a lovely patina through age and wear. The only weak point is the leather closure strap which has been stretched and worn by use. It's still in tact but only just. This can, however, be easily renewed/replaced.
