It looks like a very nice instrument, but I note that there is a lot of borrowing/extension. In reality, if my count is correct, there are only 22 ranks in that organ, though several have extensions: 6 in the Grande Orgue; 10 in the Recit Expressif; none in the Positif (all borrowed); and 6 in the Pedale. That, of course, is not necessarily a bad thing, but it does make the Stop List look a lot more impressive than is reality. I'm not enough of an organist to know if that scheme of rank usage is a good one--I'll leave that determination to experts such as Soubasse32 and others here. (Note: I only counted the Fourniture II-IV as 2 ranks.)
