vintage West Germany mechanical music box, wind up wood carousel horses

Vintage wood music box with label marked West Germany. This is a carousel about 6 1/2" tall overall. Music box plays 'Der Frohliche Wanderer' and works just fine, but the little horses are cracked, and don't spin around on their pins reliably, though the music box base turns around as it should. The pins spin, the horses just need a little work!
