This flute has a rosewood body with thirteen silver keys. The rims of the holes are also in silver, and so are the rings between the four parts that form the instrument. This instrument is an excellent example of the extensive production that the Viennese company Ziegler maintained throughout the 1800s, reaching the production of twelve-thousand specimens a year in the final quarter of the century. The Ziegler flutes, which have a typical model of holes, keys and, hence, fingering to be adopted, made a remarkable success both in Austria and in Italy in the 19th century. This is the cause of the considerable delay with which these countries adopted instruments based on the revolutionary model designed by Theobald Böhm (1794-1881) in 1832-1847, which is to date the traditional model for orchestral transverse flutes.
