This style stethoscope developed by Dr. Robert C.M. Bowles in 1894. Original version has a flat diaphragm chest piece which could be used alone, or with a short rod that screwed into the diaphragm to localize heart sounds. The chest piece could be connected to a binaural earpiece, or could be used alone by applying the ear directly to the hollow opening. Early versions of the Bowles stethoscope had only the diaphragm chest piece but later models (referred to as "combination stethoscopes" had both a bell and diaphragm interchangeable in the same chest piece. George P. Pilling & Son Co. of Philadelphia was the sole manufacturer of the Bowles stethoscope in America from 1900 to c. 1950. [Ref. 3] - Area Notes
