This mouthpiece is Model MF3 by Mike Finn Mouthpieces. It's in good condition but there is a slight dent in the neck of the mouthpiece.
From the manufacturer:
The MF3 boasts a wider inside diameter and a deeper, more funnel-shaped cup. It features the same slighlty rounded rim contour as the MF2 for above average flexibility, comfort and ease of articulation. This is my most popular design, providing a rich mellow tone in all registers. Retails for $205.
Size: 1.73" diameter x 4" long
