This little Vintage Wooden Swiss Chalet plays, "Der Kobu u der Chrigu u der Sepp" on an 18 note Lador Mechanism and it measures 4 3/4" x 3 1/4" x 3 1/2." It was obviously made for the European market.
It is a sweet yodel tune and you can hear it on You Tube. Click here to hear the tune sung (as a vocal, not as a music box).
We couldn't translate the title but it is a charming tune and delightful in this music box (not sung as a vocal).
