Yeah, that's great. In [1], you can see it (Joan's organ) in its original state. If you follow the youtube playlist, you can see the amount of work it took to get it out and install it. That organ has some 15 stops, many of which are "borrowed" (i.e., the 4" uses the same pipes as the 8", but plays an octave higher), and it doesn't have much wind pressure. So it is small. The organ from the link has 117 ranks, and its pipes extend far beyond Joan's organ, and it fills a hall instead of a small parish, so it is huge. Multiply the work done by Sam Battle (who's behind look mum no computer) by a factor ... 40?
