I think the marbles are referred to as Wales, simply because some were packaged in Wales jobber bags (I'll bet Al has one he could show us), But I have seen Cat's Eyes packaged in Wales bags too. I think some would refer to the marbles shown above as "Pincers". They're a little different than the Japanese "Mt. Fuji's" Al posted in another thread (and I copied below.)
The "Pincers" are a brushed (or veneered) marble. The seams are a bit more like Master but one tends to have a real tight U-shape (like shown on Tommy's right marble).
All of this is, AFAIK.
