Coocoo Clock

Old German Coocoo Clock looks hand made, in excellent condition. My friends mom had it serviced regularly to keep it in proper working order. Has not only the cooco bird that pops out on the hour and half hour, but a carosell of people that goes around and around as well. Very neat clock! Plays a really nice tune as the people carosell around. There is another piece that goes with it that has a thermometer and two hand carved people on either side on another carosell, not sure what it goes to, just know it is part of the cooco some how. Any information about these two items would be greatly appreciated.

Good
