Antique Drinking Flask with Leather Case

Vintage drinking flask, in great condition, and from the looks of the lid/cork it may never have been used. Made in Germany, & lid has a built in shot glass (see pics). This item has very minimal scuffs and some faded spots on the front of the leather case, but overall it's in great shape for its age. Measures aprox. 8 inches tall, 4.5 inches wide.
