Teacup and Saucer?

[Christian A]

Can someone please help me identify the manufacturer, year of teacup made, and any history of the company?

Any info is really appreciated.

Thanks,

Christian

This site explains the diamond and it's components: Pottery -* Registration numbers and diamond
it looks like a letter x (to me) on the right hand side, which seems to indicate 1868

Hi,
It's from about 1865 to 1875
That's all I could get from the research that's on it,
The cup is hard to read.
Sorry but hope that helps??
