Paul-Son H&C first made in 1964

Paul-Son 1st chip production in Las Vegas was 1969 per Eric Endy.
Paul-Son moved production to Mexico in 1985
Paul-Son 1st inlayed house mold Tropicana 1972. Made at Burt, shipped to Paul-Son

If the Cuban was a PS chip it was made after 1972, IMO.

I don't think that house mold was ever made at Burt. David might know.
