This is in excellent condition, and marked inside as shown. I do not have the key, and there is one raised line mark on the top lid which I show in my last photo for you to see. This measures 20 1/4" wide X 5 1/2" high X 7 1/8 deep. When you lift the lid, there is a hinged glass cover that you also lift and on the left there is a lever to pull that makes this music box play. There are 3 knobs on the right side to operate this as well.
On the underside there are some pencil marks that I think are there from when this was actually made. This is a large heavy music box that weighs 19 3/4 pounds.Please look closely at my photos for details.
