I recently bought one of these, complete but disassembled and including a capstan winch as well for £150. It is the even rarer mk1 hydraulic winch.
Only problem is that the dowty pump is fitted with the (unbelievably rare) adaptor casting for the early rangerover/stage 1/101 fc gearbox instead of the casting for the land rover series gearbox. Just need to turn up an adaptor on the lathe to enable it to fit the series box as I cant find one to fit the series box.
Mine is all fitted to the truck with the exception of the pump. Happy to discuss swapping your series pump for my ultra rare 101/stage 1/rangey pump if you like
