This is a nice Berg tenor piece with curved machine marks on the table. Bergs typically measure about 0.05 narrower than they are stamped, so this piece is more like a .115″ opening. It’s not hard to play and responds easily with a little softer reed than you might use on a .100 for instance. It has a big open sound that is straight ahead and that can cut through if you need it to, without being overly bright or harsh. It comes with its ligature as well.
