WANTED: Lotus Esprit ABS pump (with housing)

I’m looking for a working ABS pump (complete with the aluminum housing block) for a 1994 Lotus Esprit S4 with the Powermaster III Delco Moraine ABS braking system.

I don’t need the pressure switch or accumulator, but I do need the aluminium block they fit into. Having said that I would be interested in the pressure switch & accumulator (but only if working) if you also have them for sale.

I’m in the UK, so please get in contact with a price.
