A Hungarian woodwind instrument that resembles a Soprano Sax in construction but it is made of wood. The bore is tapered like a sax, not conical like a clarinet. It comes apart into 4 pieces like a clarinet but has no tuning barrel. It may be pitched in the key of 'C' or it may be in Bb. They may have been made in different keys but the ones I have seen or read about were all in 'C'. It has a simple kind of key system like an Albert system clarinet. Original case and MP in good condition. No makers name seem. Close crack bell and top of upper joint. All keys are working well. A few pads are absent.
