The Cinelli's have a cone shaped expander as opposed to the usual wedge. Nothing at Niagra. Any other ideas?

Thanks

Google.

I think I have one I won't be needing (see my thread about the Peugeot CFX-10).

Find a trashed 3TTT stem, same expander. Same with Modolo.

I was recently wondering this myself since I am thinking about building some custom quill stems. I think these parts were pretty rare even when the stems were in production. The stems were more likely to break than the bolt/wedge.

You might end up buying a whole stem, just for the bolt and cone. I have two Cinelli 1R stems that I don't want/need, but don't want to piece them out.

Right you are. I did that once.

Seriously, I wasn't joking. I have one, PM me if you want it. The stem bolt itself is a little bent -- I'm not sure how much of an issue that is.

A while ago, I was so hard up for the bolt/wedge, I cut off the bolt at an angle and am using a wedge nut and bolt.
Now, with 2 3TTT stems and 1 Modolo, I'm flush with stems way too long and the cone bolts/nuts that they have.
