I think the main internal spring which attaches the body of the mech to the cage had come out. This vid shows how to access it and re-fit.

Sometimes those pins are removable but I don't think they on that mech, I think I've forced one round before years ago but I'd probably look at trying to dismantle the cage, at least partially first now.
