Hi James,
I'm also quite new to CGAL, but from what I understand there is no built in
way to do what you ask.

You can either go over the vertices with an iterator/circulator looking for
the one that has the right info (inefficient I guess), or have some
book-keeping container (vector, list etc.) that stores the vertex handles.
e.g. I am using a vector of vertex handles constructed such that the index
of the vector element corresponds to the info of the vertex to which the
handle belongs. That way when I want the vertex handle of a given index, I
just go the the vector element of the same index.

Hope this helps.
Yoav.
