[Engraving] None (No personal names or other engravings) Engravings such as "Littmann" are present (see photo 4) [Product Condition] There are some stains as shown in the photos, but there are no issues such as broken springs! Perhaps because it has not been exposed to sunlight, the tubing is as soft as when it was purchased, and the sound is clear!!
