Dug through the box and found the goodies below:
And, a correction: A 9.3 bullet WILL fit in the small end of the 'base'. I probably grabbed one with a flaw or something that didn't fit.
There were also these two items. I tried to get an internal picture but can't. However, there is a captured spring inside each. Neither of these will fit into the small end of the kugelsetzer but will fit over a 9.3 bullet. I assume one places a bullet in the end of the tube and then inserts into a loaded case...maybe? Any thoughts?
