Rails and tip are in excellent condition. No teeth marks on the beak as it has always been played with a patch.
7M is a tip opening of .105 with a medium chamber.
Easy blowing with a big and focused sound.
Here's a link to the specs given by Aaron Drake: http://www.drakemouthpieces.com/-Son...nt__Tenor.html
All is included: the original box with the cap, reed binder and pouch (the latter not in the pictures as I only found it afterwards).
Price: $245 plus actual shipping costs (from Belgium).
Happy to answer any questions!
