Huuuu,
"Wine" pattern must be relatively old, I foound it in CGR 1957/9 - pattern number 19834 - also in Marcus's database. Seem to me that 20311 is a bit refreshed 19834, rim looks less precious. I suppose that it was produced also after privatisation, I saw complete set of big bowl + 6 little bowls labeled with Libs paper label at flea market today.
