Which Tasmans are we talking about..? Mark I, or Mark II..?

I've got a set of Mk II's (my second set), which I've got to get tidied up and put on my car. It has, in places, undamaged tapers in the face of the wheel, where the washers sat. So, my understanding is that Mk II Tasmans had tapers on the wheel, washers with a taper on one side, and flat nuts.

I've also got damage on my wheels from where people have used flat nuts/washers, and simply tightened them until they chewed up the alloy on the face of the wheel...

Given this, my plan has been to (eventually!) get all four wheels faced flat for the nuts. Then I'll be after some nuts and washers... I've got a few here that fit, but they're assorted (i.e. every one is different), a bit tatty, and have corrosion and gold paint on them.
