Keilwerth New King
This model has the rolled tone holes and the beautiful (or ugly, as you wish) plastic screen. You can find more of the history of this instrument: http://www.saxpics.com/?v=ser&manID=9 It is a very solid instrument, used a lot but technically is a very good shape. It is a very freeblowing instrument with a clear sound. You can whisper on it, but you can also play super loud without any effort. The sound is nice and clear. A very good budget instrument!
