Wawel China Tea Set

The pattern I believe is called "Tea Rose" from 1938 The picture shows a serving bowl and a creamer, the creamers handle is broken off, I knew that buying it but the serving bowl broke during shipment. I paid a total of $40.00 for the set and I think is a great buy even with the two broken items. Don't know how much this would but I'm not palnning on selling it ...well ever. I hope someone has some info for me such as what do the numbers on the bottom mean? there are alot of number1's and a few 2 and 3's and one number 14 and 4 on the bottom of the tea pot.

Good
