what are these old tools?

Recently I bought some great old bodyworking tools from an estate auction (posted pics in the recent finds and buys thread) and one of the things I bought (a bullseye pick) came with a bunch of body dollies, but also these two things. I can't figure out what either of them is, and Google Lens was no help. Anyone know?

The cones seem to spin or be removable from the one piece, I thought maybe for packing bearings but I can't figure out how it would work. The other thing is heavy but feels like steel and not cast iron, although I could be wrong. They're both round, so the back sides look just like the fronts. Anyone?

 

Top one looks kinda like an axle for truing motorcycle wheel.

 

I think the iron one on the bottom is a lot older than the top one . It looks like an alignment tool of some kind .I agree the 2 cones on a shaft could be used for truing a spoked wheel.

 

The spoked wheel thing does make sense, the guy did have a bunch of old bicycle/motorcycle style wheels in his garage.

 

I agree with Pete that the bottom tool is some sort of alignment tool.
Tapered to accommodate various diameter holes, I imagine it would be used much like a clutch alignment tool or an iron workers spud wrench.
Possibly used in an assembly type shop such as a machine shop or foundry to rough locate tooling in order to cinch it in place.
Possibly in the field for repairs on railroad or heavy excavating equipment for something like lining up a bucket, etc to be pinned/bolted in place.
