These little Vintage revolving Wooden Swiss Chalet scenes, wind from the top (clockwise) and this one plays, " Sound of Music" on an 18 note Swiss Reuge Mechanism and it measures 4 1/2" in diameter and 4" high. the roof lifts for maybe placing a ring or small pendant. They are all hand-painted with careful detail and some variations.
It is sweet and in excellent condition. Probably not played much. It also has a wooden off/on sliding thumb piece to stop the music without lifting it from its place. They don't make them like this any more. Today most usually, the music on chalets are left to wind down.
