Wow, I just picked up what seems to be an original Schuna tárogató on eBay international. I hesitated to bid, because it is very difficult to find any information about Schundas, as opposed to Stowassers, which are all over the place. I did find some pictures of a Schunda at the Horiman collection page in the UK. The maker's marks match, and while the keywork is somewhat different there are telltale similarites in design of the tenon rings. key attachments, and the fact that both low B and C# key arms arch over the D# keycup, instead of the more common design of having the C# arm arc around the key. I will let you all know more when the instrument arrives. Schunda or not, it appears to be a very high quality instrument, and is in incredibly good shape. In the meantime, if anyone has any links to information on Schunda tarogatok, or knows any experts who might be able to help me ID the instrument, please let me know.
