The script in the label is troubling. The characters in the middle of the name appear to be "ll" with curious descenders. (Compare these with the "s" and "l" in "Breslau"). The name "Gellner", however, is not found in the New Langwill Index. Friedrich Gessner of Breslau is listed and fits the apparent time period of this horn. A flugelhorn by Gessner is known, and is clearly labeled in cursive script.

Friedrich Gessner flourished in Breslau, Germany from 1900 until after 1934. He succeeded E.G. Heidrich ( - 1904) who flourished in Brealau from 1867 to ca. 1900 and was reportedly the chief supplier to the German Army.

The two patches on the bell of this horn testify to a history of regular long use. The triangular pattern of the valves was common in the second half of the nineteenth and early twentieth centuries. (See another example by Josef Müller). The double horn of M.Jiracek & Sons is a modern example.
