The Aquincum Organ (need help real quick)

[Eleatic Guest]

I am currently in Budapest, trying to chase down the world-famous Aquincum organ, the best preserved ancient organ. But I cannot find the original Roman pieces. The Aquincum museum has both reconstructions of the individual pieces and full-fledged models, but they say the Budapest City Museum has the original find. So I went there, but they in turn said the Aquincum museum holds the original parts too. Which they do not because I checked every item there. The Hungarian National Museum does not have the original Roman pieces either, so where is the original Roman Aquincum organ?

I would appreciate a real quick answer because I will only stay one more night here. Thanks in advance
