But after I got it home and looked it over more carefully now I am not so sure, I could not find any way for the collet-like things (of different diameters) to expand when I screw in the handle. There is a knurled nut on the end of the short pipe that will expand the black rubber sleeve, and presumably expand the collet thing that is over it, but I do not think there would be enough force to in the squashed rubber sleeve to expand the collet to flare out a muffler pipe. And there is this white plastic cone thing that I am not sure what it would be used for, it would not stand up to being forced into a metal pipe, and not much else either. The two length of pipe screw together to form a handle, the longer one has a fixed knob on the end, and the collet-like thingies attach to the end of the "handle". the collets are held together with a number of black rubber bands that look like large o-rings. The guy I bought if from had no idea what it was used for, he said it was left behind in his garage when he bought the house. It looks like a handle that is used to hold something on the end by expanding it to friction fit in the end. Perhaps a tool for installing something inside where it is hard to reach?
The case looks like a copy of a Snap-on or similar auto-tool box, there are no markings or identifying marks are it at all, not even a logo or "made in xxx" label. I thought it was a Chinese copy of a snap-on tail pipe tool, but it may not be an automotive tool at all.
I did not spend much on it, so I am not too concerned, but I thought perhaps someone on this list might know. Your guess is as good as mine.
What is it? Anyone seen one of these before? How is it used?
