This is a consignment item. It is a flask that measures 3 1/2” x 5″ x 1/2” and holds 5 ⅔ ounces of liquid. The flask’s front features an attached Prussian Army Pilot Badge that is vaulted to match the flask’s contours. It is also quite thin, so it is probably NOT a style that a pilot could have actually worn on his tunic. That said, the badge is attractively detailed. The flask is made of metal, perhaps pewter or some other base metal. It has a screw-on top that detaches from the flask. The flask’s exterior sports a tarnished surface (I love seeing this kind of patina). The flask’s base displays what looks like a hallmark and several numbers.
I can easily picture a pilot slipping this flask into his tunic or flying coat and having a nip, either on the ground or in the air! Personality aviation pieces like this are difficult-to-find.
