I can't think of any military aircraft where the pilot/nav seats were bolted together side-by-side. In fact in most if not all Mosquito variants, the crew seats were also offset longitudinally from each other.
My money is still on pax seats (the tray attachments would support that) and, assuming the DH part is correct, likely from a Comet.
