So where does the plastic facia fit to then? I thought that it was attached to the colour face (although why I thought that is another matter).
The bolts go through both the plastic fascia and the clear-plastic face. The two pieces of facia (black part and clear part) interlock together and are both held in place by the bolts. The threads for the bolts are mounted through the display board onto the frame.
Are the bolts exposed out through the plastic?
Yes, the hex heads are visible, and they are clearly seen in the renderings and photos at the web site.
Does this mean that I can have the option of not having the plastic facia?
I assume you mean making it look like a MK1, with a smooth flat clear/colored plastic part. Well, not really. I mean you could probably take just the black bit off, but the underlying clear plastic part isn't plain and flat any more so it would look goofy. I saw the SLA model in San Jose, and the clear part of the face is sculpted to interlock with the black part. Plus the sculpted handle would look goofy.
If you had the parts of a MK1 still, you could probably drill a hole for the knob and fit that to the front of the MK2. It would still look a little odd, though.
No, wait, on second thought, you couldn't even do that. The clear/colored plastic part has some kind of special IR filter applied to the inside of it just over the IR sensor. This is necessary so that sunlight doesn't screw up the IR signals. On the MK2, the IR sensors are in a different place so you'd lose that filter if you did that.
