vintage hand-painted milk pitcher, stoneware pottery w/ S bar mark

We really like this pretty flowered pitcher, but we haven't been able to identify the maker of this pottery, marked with a barred S mark. If you have any information about this stoneware mark, please email us, we'd love to hear from you.

The pitcher stands 4 1/4" tall, a large creamer, or small milk pitcher. This has some fine glaze crazing, but no chips or other damage.
