The diasq mold was used from 1941 - 1960, but still made for non Casino up until 1990, that explains the B-B mold and maybe this ship and chips are from the Italian cruise ship David has posted and not a California ship chip. Very interesting because I have looked up this ship before and figured maybe it somehow came to California ? Since the chips were listed so. Another set of chips I'll have to pull out of my California section. I'll have to start a European Ship page. Torrey
