Need help identifying pottery stamp

[Karen from PA]

I am interested in possibly purchasing a piece with the attached stamp and spent hours researching the stamp. Having no luck. It is located on the bottom of a wash bowl and pitcher set. Does it look familiar to anyone? Thank you.

I can't make out that Second word.

I Think Royal Tradition? but I'm not sure on that second word.
it doesn't seem to have 9 letters

Royal Ironstone is what it says... but I don't know the where/when stuff, yet.

A clue: [FONT=&quot]Pieces bearing "[/FONT][FONT=&quot]Royal[/FONT][FONT=&quot]" can usually be dated after 1850.
