This vintage barometer is in very good condition. No plastic - the face has beveled glass and the back is made of metal.
It is a little over 5 inches in diameter (not including the hanger). I don't know what kind of wood the barometer is mounted in, but it has very pretty graining.
Made by Welby in Germany. A very nice piece that is hard to find, especially in this condition.
