The number 3666 on a tea set typically indicates the manufacturer's mark or pattern number. It may refer to a specific design, model, or type of porcelain used by the manufacturer. Often, such numbers can help identify the age and origin of the set, as well as its potential value among collectors. If you're curious about its specific history, researching the manufacturer associated with that number can provide more detailed insights.
