I took off the keyboard and cleaned underneath. I did a deep cleaning throughout. It still.need some detail cleaning especially at the string posts. It should just need tuning and play. (Every stringed instrument ever made in the history of stringed instruments needs to be tuned before playing the first time and pretty much every time after you play) The solid wood box is wicked cool. This antique Columbia No.3 Zither with Case is a rare and special edition commemorative item, featuring a nautical musical motif that includes elaborate harps, boats, and sails. The zither is a 31-string fretless autoharp, handcrafted from cherry wood, lacquered with a black finish, and produced in the early 20th century in Jersey City, New Jersey, USA. This instrument is perfect for shabby chic decorating, as well as valuable concert playing. It comes with a custom bundle that includes a metal piece and a hard case. The zither is in great shape, weighing 7.5 lb, with a length of 24 in and a height of 15 in. It is a right-handed instrument and was made for players of all levels. This vintage zither is a true gem for collectors and enthusiasts of the Victorian era, turn of the century, and early 20th century.
