If it's down to alterations, just how many organs are left that havent been altered over the years at some stage? The civic's voicing is entirely original, which John Compton oversaw himself. The only alterations has been additional ranks, expansion of the specification, and the removal of the melotone by Arnold Richardson. If that's the lottery's way of thinking, then it's a wonder they give money to anything at all. I think partly the problem might be that it is part theatre organ and not strictly straight. However as you say, that does not distract from it's quality, only made it what it should have been from the start.
