Schmid Music Box

This is a music box I love. The characters are exquisite and the movement is very sweet. My 2 year old daughter and I stare at it for long periods of time. I can't find anything like it except for some 1960s Snoopy Red Baron pieces that don't appear to rotate. There are a few little things missing (one of the guitars that the little Romeo dude is holding, the window ledge, and the flags on top of the turrets), but I plan to restore it. Does anyone know anything about it?
