20th century English tea cup

[Ninjafossils]

I found this china by my 1750-1950 site in pieces. It says "old castle W England". Any ideas?

The W is for wedgwood they have quite a few designs not sure of age though. Google old castle england wedgwood tea cups.

Ninja. It looks like flow blue transferware. All that means is that it's not handpainted. Here's a link to Ebay of a plate that similar to yours. If you look at the description, you can see its the same mark. Circa pre-1891. I couldn't find this mark
associated with Wedgewood. I'm not positive, but I think it might be Johnson Brothers.
