The one fitted to my Bonnie has a plastic reservoir, not entirely sure what it's off but I think it's early Land Rover. The clutch is nice and light too.
It could be this one but can't be certain it will fit straight on as it was fitted when we got the van but it looks the same and that was well over ten years ago. It does poke up through the hole in the floor slightly so you may need to make a new cover plate.
