As far as I know, as of this date, the only type of CREB133s for which the hobby knows what would make up complete set of SNs are the large, chunky Cauvet pieces where the SN is in the middle of the crown below the word (arc) BROOKFIELD. From what I can tell people generally consider these the first ones made.

I have a picture of two of the very rare SN8s that were at a Springfield show some years ago now. Sorry I do not remember much of the story except one was brought by the Plunkets. In hand the profile of these is a bit different than the others of the series.
