3M Littmann Classic III - Raspberry tube, Copper Chestpiece, Raspberry S

Two-sided chestpiece with tunable diaphragms on both the adult and paediatric sides.

Single-piece tunable diaphragm is easy to attach, and easier to clean because its surface is smooth without crevices.

Paediatric side converts to a traditional open bell by replacing the single-piece diaphragm with a non-chill rim.
