A few days ago "Riverboat" Rick asked questions on inlay sizes as refered to in TCR. The 3 sizes are "Round" "Oversized Round" and "Over-Oversized Round". I believe most of us use these reference terms. A look back in a GPI (Paulson) guide defines it this way. There are 3 inlay sizes, A= 7/8" called standard, B=1 1/16" called grand and C=1 3/8" called giant. Although few use the GPI names the 3 sizes are commonly used to determine (Round) (Oversized Round ) and (Over-Oversized Round). Full Graphic would be as on a Chipco chip. The attached scan shows the 3 sizes. Old info for some but useful for others. Hope this helps, if anyone wants to add to this, fire away.
