Vintage German Barometer for on the Wall, Made of Wood, Brass and Glass

This is a charming and very interesting vintage barometer made in Germany. It is made of dark wood, brass and glass. There is a brass loop at the top for hanging on the wall. All parts have patina and mild scratching. The wood has some wear and there is dust under the glass. Please have a look at the pictures to appreciate the charming character of this piece. I don’t know if it is in working condition. I think it is beautiful for decorative purposes. Marked: ATCO Germany 5” wide 1.75” deep 6.25” tall with loop
