Vintage German Barometer for Wall Wood, Some Patina Weather Station

This is a charming and very interesting vintage barometer made in Germany. It is made of oak wood, brass, and bubble or convex glass with a hole on the back for hanging. This has some heavy patina on the brass and some scratches, as seen in the photos. The glass is domed. Please have a look at the pictures to appreciate the charming character of this piece. I don’t know how to test if it is in working condition, so I am selling it for decorative purposes only. Made in Germany 13” tall 5” wide 1.75” deep
