Maybe this Breitschwerdt rocking horse from the 70s is in such good condition because no one ever played with it. I'll go ahead and assume that it rock-steps forward, otherwise I can't account for it.
Breitschwerdt was supposedly a toy company known for products of high design and educational value. But except for this [admittedly nice-looking, if plain] horse, the only other toy I've found is a random jumping jack on eBay.de. Anyone?

I lived in Germany in the 70s, and I got the distinct impression that Germans did not want children to have fun. Probably no children were allowed to touch the horse.
