A friend of mine had 2 of these things in his shop when he moved but had never seen them used, nor any idea what they were for. He figured they had to be good for something and guessed that I might think of something so he gave me one.
It's all pneumatic and came with no tooling at all. It indexes through 8 stations and can be made to stop accurately so I thought I might try automating my reloading press. So far I've made 8 shell holders, the ring which will hold the tooling, and a frame to hold it all together. Shells are loaded at the 5 o'clock position, decapped at 6 o'clock where the tall tower is mounted, primed at 7, inspected for primer at 9, etc.
