Grumpy's pump organ

I should have known better but I went on a 5 minute internet search to see if there existed anything out there that could have been the inspiration for the organ. Nothing. Not even close. I knew it was pure imaginary. Never mind the obvious humorous touches like the bird and the booty bellows, the whole idea should have seemed preposterous, but I'm not an organ builder, so I searched to see if there was anything close. I doubt old music instrument experts waste their time on IMDB, but perhaps one will comment. I learned harmonica tech goes back to old China. Quelle surprise! I mean it's obvious from the movie there are no mechanisms metal or wood that open the valves/caps. The whole thing is like a griffin. A impossible combo of recorder, organ, probably a holding chamber like the bag of bagpipe. If such an expensive hand-made technological marvel did exist, it could explain where all their money went from the mine which yields gems already cut/faceted.
