The listing, Marine Band Harmonica has ended.
Used but given tender loving care by my father. This harmonica is in the key of B flat and comes in the original box. If you wish to clean the exterior parts such as the covers, mouthpiece, slide, etc, use a soft cloth with either soapy water or rubbing (isopropyl) alcohol. If you disassemble your harmonica before cleaning, wait until the parts are completely dry before reassembling."
