This is an antique lap zither of the type with an added 5 string guitar neck on one side.
If you are not familiar, there are forums and and other listings that explain details about this unusual instrument.

The printed label inside this one has faded enough that the manufacturers name is visible but not readable.

All 5 guitar neck tuning keys are working fine, not sure about the piano style zither tuner pegs.

Missing 4 zither strings and 1 guitar neck string.
Missing several of the metal posts below the piano style tuners.

All strings are loop end style.

The body of this zither is in very good condition, no cracks or dents or notable scratches.

Appears to be made of beautiful Mahogany of some type.

The top binding is inlaid not painted.

Has 3 holes on the back side where a tripod stand of some type was probably employed.

No case, but will be packed carefully for delivery.
