You are bidding on a Vietnam War era US property marked sphygmomanometer and a stethoscope ! The stethoscope is German made by Riester and has a 2 direction valve and works great! The sphygmomanometer is made by Propper and appears to be in good condition, however when I squeeze the bulb it is full of air and does not deflate, I definitely don't know how to operate one of these, so it may just be operator error. Buyer to pay $12.90 for shipping and insurance. Thanks for looking, and good luck bidding!
