Lortone Gem Sparkle 33B-NR Rock Tumbler 2 Barrels Drums Carborundum Co.Pulled out of an old barn in upstate New York. This industrial rock tumbler comes with what you see in the pictures. It has two containers with lids. I'm not an expert on this item. The red rod but I'm pointing to in the picture rotates when plugged in. The other rod moves freely but does not move when plugged in. The container is filled with a black fine dust that was acquired with the item.
