My mother had a set of Royal Albert - Pettite Point - some of the pieces got broken over the years, when I inherited it, someone told me to check with the following people, and even though it was discontinued I was able able to replace and finish off the other pieces as well. Pic attached to show pattern. We try to use it whenever we can.

They have over 3,000 patterns in stock - so if you are missing some of your pieces you may want to look at this site. They also carry silverware and crystal. Nice people to deal with.
