This vintage Sonotone hearing aid set includes original air conduction receivers, receiver cords, and personalized eartips. Each component has some or perhaps its original packaging, reflecting its authenticity and collectible value. The cords are intact with plugs, and the eartips are personalized with names, adding a unique historical touch. The items show typical signs of age but remain well-preserved for vintage hearing aid collectors or enthusiasts. I cleaned them up the best I could, but the insides of the eartips can use a power wash. I don't know if they work, these are for parts. Can't see the date on the postmark, but it was when 10 CENTS would send a small package.
