I'd like to know the same thing. I have many pages of Paulson samples with different colors, different inserts (no. and color), different size and shape inlays, and different diameters. I haven't seen a cataloging system before. I know the abbreviations that TCR uses with # of inserts, OS and OOS inlays, colors, etc. but it doesn't seem to be all inclusive.
If somebody wants to make up a system, I'll send you scans of my PS sample collection so you can see what the challenge is. There are color names for Paulson chips, but no number codes to my knowledge.
