This just one of many wonderful pictures of a Russian Bayan Factory on the blog of Sergei Mukhamedova.http://ottenki-serogo.livejournal.com/177743.html
The page is in Russian but can be translated by Google Translator.
Now, keep in mind not all translators are equal (some are much funnier than others); Google Translator claims the factory as founded in 1930 and residing in Tula, which may well be accurate.
