Vintage Thermos No. 87 1/2 Vacuum Bottle

This item is a vintage Thermos vacuum bottle, specifically identified by the context as 'Thermos no. 87 1/2'. It comprises a main cylindrical body and a detachable cup that also functions as the outer lid. The main body features a black painted exterior with a distinct horizontal red band, bordered by thin gold or brass-colored lines, encircling the center. The top section of the bottle, where the cork stopper is inserted, is made of a threaded silver-colored metal, likely aluminum or nickel-plated brass, showing some tarnishing and minor scuffs. A natural cork stopper, well-worn and slightly darkened with age, is visibly inserted into the top opening. The detachable cup, also made of silver-colored metal, is heavily tarnished and shows significant wear, including scratches and what appears to be a worn-off or obscured logo/marking on its side. The interior of the cup is not visible, but its exterior design suggests it functions as a drinking vessel and a protective cover for the stoppered thermose. The black paint on the main body shows signs of scuffing, scratches, and loss, revealing the underlying material in some areas, particularly along edges and high-contact points. The red band also exhibits some wear and fading. The overall condition suggests considerable use and age. Given the 'Thermos no. 87 1/2' designation and the aesthetic, this item likely dates back to the early to mid-20th century, possibly 1920s-1950s. The construction indicates a durable, utilitarian design typical of vacuum bottles from that era, focused on insulation for beverages. The visible wear adds to its character as a historical artifact.
