After professional refurbishment (see albertharp.com for details), the nails were replaced with stainless steel nuts and bolts, making this 1896 more airtight and easier to clean. Also, the cover flanges were modified to increase volume. Basically, this is a Marine Band Deluxe except for the comb - it has not been lacquered because lacquer makes the sound less woody. Includes a Hohner Marine Band Box.
