Condition Notes:
This set is being sold as an untested, historical collectible for display purposes. The main unit, plastic casing, and paper booklets are excellent. The vintage batteries are historically intact but expired; one of the 412E batteries shows very minor age-related swelling on the bottom edge and is stored safely outside of the hearing aid compartment to preserve the device. The fabric harness items show minor expected vintage discoloration from storage but remain fully intact with strong stitching.Please see the high-resolution photos for a detailed look at the exact items and condition you will receive.Shipping & Handling:
Will be packed with extreme care using bubble wrap to ensure the delicate vintage plastics, paper elements, and original boxes arrive safely. Ships quickly with tracking.
