Rare! 1950s gold plated brass Berg Larsen baritone sax mouthpiece 110/2 offset SMS with a bullet chamber. These are the rarest of the rare Bergs and they were only made for a very short time in the 1950s. You almost never see these, and this is a great tip size. It measures slightly larger at around .112 and has a warmer sound than stainless Bergs. It has a rich, big warm tone. This is a great piece for a player or collector.
