The strings that are in tune have a lovely sound... There is a crack on the side.... And I guess someone tried to repair it with staples.
A little sliver of wood is loose on the side of the Fret Board... Just use some wood glue. After that, the Company used serial numbers. The tuning knobs all work.... So, get some strings, a Key, and some wood glue.....
