Chip order scans have been placed on Chipguide, which are an excellent record to know some chip values that are not registered, or even from casinos that no longer exist or were not known.
The cards are from The Burt Co. And since I have some questions, for which I thank you for your help:
- SCROLL mold
The first two cards shown here are for ordering chips from the Spanish casinos CASINO CASTILLA LEON (1985) and CASINO BAHIA DE CADIZ (August 1979).





Currently, the SCROLL mold chips are manufactured by the Spanish company HISPANIA, which was founded in 1987 (therefore it did not exist at the time).

Questions
- SCROLL mold chips were manufactured by The Burt Co. ??
-What year did The Burt Co. end?
- Has the company Hispania purchased the patent for the SCROLL mold?
- Entities that ordered chips from The Burt Co:
The cards show that the orders were not made directly by the casinos, but were made by other manufacturers. EWNIG Mfg Co, CARO & Fils. A. B.P. (Casino Suplies) Ltd… ..
It seems strange. WHY IS IT? Would these work as resellers ??
