Thanks. The ADC (American Diagnostic Corporation) Proscope 640 Sprague Stethoscope is the best current replica of your Rappaport, in length even.

@@markyu9636 Thanks for the info. If the Japanese endorse it, it has to be good.

It is better for hearing middle frequency sounds and is good for getting an overview of sounds around the chest before tuning in to high frequency sounds with the flat diaphragm and low frequency sounds with the bell.
