Hmmm. Sorry, that's a new one on me (So I've filched it
) It looks to be an effective ornament, and the pieces are all letter keyed, so it shouldn't prove too difficult to build.
I do already have Chandler's Galloper, which is probably as good as they come for a Horse Carousel, but what I really, really want is a Chair-o-plane like this ...
or even this will do ...
But needless to say, these are both plastic.
