These are actually the Selmer "Super Action", but most people call them the "Super Balanced Action".  The previous model was the Balanced Action and then Selmer came up with the Super Action title for this model, the model right before the Mark VI.  Super Balanced Actions differ from previous models in that the tone holes for the right hand keys are radially offset, as opposed to in line. This was one of the innovations that is responsible for the Mark VI and Selmer as a whole's reputation and is a standard on all current horns.

Re-lacquered and in good condition.  This one includes a letter, from Selmer USA, stating it's approximate date of manufacture.

We will include our $1150 Sax Alley "Complete Mechanical Restoration" with this alto, so it will play better than new when you receive it, if you click on the "Repair Option" button when purchasing.   Otherwise, you will get this alto "as is" and your favorite local tech can work on it for you.

Comes with a hard shell alto Case.

Shipping cost is extra and dependent on destination.
