Littmann 4100 Electronic Stethoscope w/ Case Gray/Black Cardiology Use

Littmann 4100 Electronic Stethoscope w/ Case Gray/Black Cardiology Use. Good condition. Works as supposed to. Only thing I know is wrong with it is the diaphragm came off and I ordered a gray and a black diaphragm for a 3100 that fits but wants to come off. Both will be included. Upgraded to Eko Core so don’t need anymore. Comes with a case and extra batteries.
