I'll add some more information to that.
The Scroll molds (and also the Jockey & Trident) were personally owned by Jeff Lindsay, formerly owner of TCS John Huxley.
He licenced (for a fee) the use of those molds to various other distributors (like A.B.P., Hispania etc.)
All chips were made at the Burt Co.
Incidentally, you referenced A.B.P. and Jaymyers. Same distributor - Jay Myers half owned A.B.P. and Huxley owned the other half. For many years they were the sole distributor for Bud Jones chips outside of the US also.
Hence although all UK based, they distributed worldwide and you'll see their names on many of those record cards from all over.

Some time after Burt Co. closed and it's replacement ASM was up and running the owner requested return of his molds. He was going to sell them to Hispania but the deal never happened and they sat in storage in Florida for years.
Almost immediately after David Sarles and I had purchased ASM (formerly Burt Co.) and renamed it Classic Poker Chips, I had the opportunity to buy Jeff's personal collection of sample chips (comprising generally one of each of all the chips made under licence on those molds). As we had just purchased ASM only a few weeks earlier I enquired about the molds and that's how I learned the history above. I was able to purchase the molds as part of the collection and David Sarles drove to the storage location in Florida and picked them up. The Trident went to Nevada Historical Society and the other 3 molds went to CPC and are still used by us today.

Those Hispania sample chips were made at ASM immediately before the molds were returned to Jeff. I guess he and Hispania thought they had a deal right then but it never happened.
