Feito em Putlitz, em 2008, baseado em J. J. Stadlmann de ca. 1750. Encontra-se também no National Museum of Natural History, do Instituto Smithsonian, Washington, D.C., USA.Parece ser o do luthier Henner Harders (ver outra postagem).
No site do Smithsonian, encontra-se a referência ao Esterhazy Machine, em que um de seus diretores toca o baryton, que pode ser o mesmo acima.
The Esterházy Machine
The Esterházy Machine—Kenneth Slowik, baryton and fortepiano; Steven Dann, viola and violin; Myron Lutzke, violoncello—takes its name from a casual remark made by Dutch cellist Anner Bylsma, who referred to the baryton, favorite instrument of Joseph Haydn’s employer Prince Nikolaus Esterházy “the Magnificent,” as “that Esterházy machine.” With six bowed strings and nine sympathetic strings (which may also be plucked by the left thumb), the baryton is indeed an unwieldy-looking instrument that might have fallen into eternal oblivion at the end of the 1800s but for the fact that Haydn wrote nearly 200 pieces for it. In its baryton—viola—cello formation, the Esterházy Machine addresses this sonically unique repertoire, while its violin—cello—fortepiano configuration allows it to play the rich keyboard trio repertoire of Haydn, Mozart, and their contemporaries.
