Hello and welcome! My name is Doris.I have been an antiques collector, dealer and appraiser for over 56 years.I will be pleased to help you.
Most probably, I will not be able to identify the porcelain factory but I can give you value if you tell me the following.-
"Sets" come in many different sizes.
Please tell me the following -
How many people does your set serve?
How many pieces does each person have?
What serving pieces are there? These can add as much as 30% to the value of a set.
Is value enough information for you but not the maker?
