Backed!
Now that I have backed, I suppose I really should find out the difference between the 'master casting' and the 'standard' sets.

Master-moulds are used to make Master-castings; these first generation castings are the best that come from the original sculpt.
Master-castings are used for Production moulding and as first of the run, are usually sent to painters for advertising purposes.
Not that there is anything wrong with production castings, of course, which are what almost all of the miniatures (99.9%) in anyone's possession will be.....
