Thank you @Brian Moore. No, it was developed in Xtol by the lab I was using at the time. I only got back into home processing (all with caffenol) about six months ago.
Thanks @Chris Bennett. Indeed, it's rather satisfying when you're able to produce something meaningful from old kit. When I had this camera cla'd I also had my old Zeiss Ikon Contina 1a (similar vintage) done. That one works like new again and produces amazing results from it's crystal clear little Novar lens.
