Interesting now I look back that out of all 4,000 pieces I got from Jeffrey, there were only half a dozen jockey mold chips.
Were all these made when he was just the distributor (or even just the hotstamper) for the mold I wonder? (and he didn't see fit to retain samples)
If so, then the original owner (I'm going to suggest ABP Myers) must have had a sample collection. I wonder if those still exist.
