Description: 7.5 inch blonde wood stethoscope with a 2” diameter and deep earpiece, the chest piece resembles a bell 1” in diameter. There is a side tube carved out of the wood above the bell leading to a rubber tube which connects with a valve like connection to the main tube and on the end has a hard rubber earpiece. This is often mistaken for a teaching stethoscope that allowed two persons to listen simultaneously. But it is not. The second earpiece gives the user an option of listening with one or two ears.
