• Got the magnet out. It is indeed a steel steerer; with an aluminium crown and fork blades (Principia fork).

    The hole in the crown is tiny and no chance the wedge is going to come out through it. I'll leave it bathing in vinegar another night (as I'm too lazy to do it right now) and have a crack at it tomorrow afternoon.

    Get something more caustic in there then. Plug up the hole in the quill, pour caustic stuff in through hole in the crown.
