Our Database Editor has researched your inquiry. Here is what she says: I have spent an hour or more trying to learn something about this pattern and mark. I believe it is the type of crown used by C. J. Mason & Co.; however, there is no instance when the mark was used alone with just a pattern name. I don’t see that I can help with the maker.

We don't yet have the pattern entered to our Database, which has 13,359 transferware patterns documented. Wish we could provide more information.
