It's a Selmer "Airflow". They play (generally) pretty badly unless refaced to a decent curve and tip opening. They open up nice, though, and can become great pieces (classical or jazz) if one is looking for a warm sound - great hard rubber. Definitely classical in original condition, though pretty stuffy playing, most likely. There are different variations on the Airflow (pre-Soloist) mouthpieces in design - some with the metal band on a smooth shank, and a few with varying scroll designs. Some of the later ones have a medium round throat like the more modern Larry Teal model (which is, in fact, the design Larry Teal asked Selmer to bring back and we now see as the LT model). I have five different tenor Airflows which span the varying shank and chamber designs. You have what I believe is one of the oldest variations.
