Rosina Bone China Cup and Saucer w/Gold trim Made in England, numbered & letter

Description

This was my Mom's
She was a collector of this type of stuff
Notice on the bottom it has the 5189 but then next to it is written "/R"
I do not know what that means
Looking at the top of the cup, it looks square
There is lots of gold trim all over the cup
The leaves are also in gold
I looked it over carefully and I did not see any chips or cracks
For some reason this weighs a little more than most of the other of mom's cup & saucer sets
We are downsizing and trying to get rid of stuff
I will pack it carefully
If you buy more than one thing from me I will try to combine and will credit you on paypal for extra postage
