The innards of the seat appear to be a custom mesh top spring unit. The mesh top is rusty and disintegrating, and it looks like a replacement is not possible, so I'm thinking either replace the whole thing with something like chicken wire, or to try and weave the broken bits back together with wire .
Does anyone have any thoughts?
Also the machine screws (2ba I'm guessing) that hold the bolts, hinges and rear cross piece to the seat base were rusted solid and I had to drill the heads off the screws to get the parts off the seat back.
Does anyone know where I might find replacement captives for the seat back?
