Good afternoon everyone, I am wondering which model number this Moeck Tuju Tenor (in C) has. It has two keys, one on the side. What I am also after is also a fingering chart. I looked at several including http://www.recorder-fingerings.com/en/Div.php?f=P&t=mMoe.bTu.3T&Aus=MoeTuT but it does not indicate how to use the side key. I tried re-sizing the image below, lol, but I am not sure how to do that. So in short: 1. Which Tuju tenor model is this? 2. How to use the side key... Thanks for your help!
