Query: Reconstruction of infinite matroids from their 3-connected minors   We show that any infinite matroid can be reconstructed from the torsos of a
tree-decomposition over its 2-separations, together with local information at
the ends of the tree. We show that if the matroid is tame then this local
information is simply a choice of whether circuits are permitted to use that
end. The same is true if each torso is planar, with all gluing elements on a
common face.
