1. The above information is for R-1819 as R-1819-S has not been found in a catalog and they are assumed to be the same design. An example marked R-1819 is not known.
2. The catalog lists three Nesting Ashtrays as a set:  R-1819 (above), R-1820 (6¾"), and R-1821 (4½")

Bottom reads:  ROYAL HAEGER R1819-S U.S.A.
