I see what 'Historic' is referring to -- Bohemian, maybe made for the American market -- the engraved script appears Germanic, while I cannot imagine Banjos being prevalent other than in the U.S. A pontil scar suggests the bottle was hand-blown or otherwise worked by hand by secondary reheating on the end of an iron pontil rod in front of the furnace opening referred to as the 'glory hole'. After the pontil rod is cracked off, better glassware has the pontil scar ground & polished. Wherever fine glass is made, the pontil mark is ground and polished, even to this day (despite our just having had the great Steuben glassworks bank its fire for the last time THIS WEEK). A couple other observations: except for the banjo connection, it looks like druggists ware -- high purity, hand made glass for the chemist/druggist (because you do not want to keep chemicals in bottles made of "common" glass because of impurities in it). Chemical wares were often made in smaller shops employing specialized glassmen, some of whom were undoubtedly German immigrants (Adolph Heisey, and Dorflinger are just 2 famous German glassmen working in the U.S. that come to mind) -- so having German script on American-made apothocary jars is not much of a stretch. Another thought: Banjo & guitar strings before a certain era (1930's?) would have been made of "gut", which is susceptible to humidity, temperature fluctuation, fly infestation and mice(!), -- so keeping gut strings for fine instruments in air-tight apothocary jars isn't much of a stretch either. As an aside, I am active in a local New England history museum where one continuing exhibit is of a country store ca.1900 (where we have to fight off mice getting into soap, penny candy, etc.). Your banjo string jar would be a welcome treasure in such a historical collection & display. There must be collectors of musical instrument history that would be very interested in seeing your gems.
