I am a frustrated RN. I work in the Dallas/Fort Worth area. I have lost 2(two) expensive stethoscopes within a year. My first was a Littmann Master Cardiology stethoscope. This stethoscope was a birthday present from my wife. It was lost about 1 year ago. The second, a Littmann Cardiology IV, was brand new. I had only used it on 2 patients. Both were engraved Moses K Thiga & Moses Kuria Thiga respectively on the tube and head. Please be on the look out. Thank you.
