Given that it would have been impossible to shut the top doors with the horn in it's present position, they have been removed.
It would not surprise me if the seller still had them lying about somewhere.
Maybe, but they're clearly not shown and they are not included in the sale. That's not worth the risk in my opinion. Why not just buy a complete one in very good condition with the correct soundbox and enjoy it straight away? I doubt it'll sell and you might get it for under a £100?
PS - Well, it's either sold (and rescued by hopefully a sensible buyer) or the seller has got exasperated by reading this thread trying to understand the baffling logic of some collectors, and promptly withdrawn it in disgust! Maybe he / she thought that someone would buy it to use for repairs of the other wreck.
The wreck is still there but the complete one has gone somewhat mercifully. If it reappears I might just have to add it to my cabinet gramophone museum.
