Lrg Junk Organ
Here’s a wonderful junkyard organ from Popular Science 1939 –

Discarded bottles, an old vacuum-cleaner motor, sections of inner tubing, and other objects salvaged from the scrap heap comprise the parts of a unique junk-yard organ recently exhibited at Atlantic City, N.J. Individual notes are sounded by air from the cleaner motor blowing across small holes in the caps of bottles tuned by partly filling them with water. Supplementary noise makers are attached to the organ’s console.
