Kalamazoo mandolin.  In the photos you can see cracks on the neck heel, the top, the back edge by the tailpiece and in the fingerboard. Also the main body brace inside the mandolin is loose at one end, it's at least a half inch above the inside back. The instrument also has some finish wear, chips and scratches.  Four of the tuner knobs are missing, the other four have cracks or chips in them.  If you tried to use them, I think they eventually would break off. Seven of the tuners seem to turn normally. The last knob turns, but when it does the main gear on the back of the headstock doesn't turn.  The pickguard is gone, you can see one remnant chunk near the neck.  Also, the tailpiece cover is there but not on the instrument.  There's only two strings on the mandolin.  The case is in poor shape, you can see several chunks of the original cover material are gone.  So all in all, expect to spend some money on repairs to make the mandolin playable.
