ANTIQUE HAND MADE LUTE MUSICAL INSTRUMENTMother of Pearl Silver Needs Repair

Description

From an estate
I am not familiar with musical instruments, but will do my best to describe.
If you have questions or concerns, please message me.
24-1/2" Length
8" Width
There are 3 strings in place and if I strum them, they do make a sound
The center opening is 2 x 3-1/2"
One of the designs on the bottom of the opening is missing
The designs on the front appear to be a combination of silver and mother of pearl.  Nothing is marked, so this is a guess
The knobs at the end all turn, when I tried to move.  I didn't want to turn too far.
The back of the handle seems to be silver.
The balloon body is made of thin slats.  There is a split down the center back that needs to be repaired.
