vintage Royal Albert china, Marguerite pattern mini cream pitcher & open sugar

Vintage Royal Albert Marguerite pattern mini creamer and sugar with pretty aqua blue flowers. The cream pitcher is about 3 1/4" tall.

The open (no lid) sugar bowl is in excellent condition, but the cream pitcher has some yellow spotting to the interior.

I'm not sure what has caused this spotting, it's not what we generally find as stains from use. I just wiped it with a gentle dish detergent, and haven't tried to remove the spots with anything stronger, haven't soaked it.
