British antique plates from 1790

Hello,

My name is Shwe Khine and I am currently living in United States.
Burma, now known as Myanmar, was under British colony until 1948.
In that time span, many British officers lived in Myanmar.
Some of them brought some wonderful plates at that time and some of these plates survived until now.
I have been contacted by a friend who is living in a town call Maulmein and he sent some interesting photos of some the plates that he inherited from his grandparents.

NOTE:: “-” are the characters that I cannot clearly read. Only experts like you will know what are these characters.

Can you please let me know if you would like to do some appraisals on them?
Plates are still in Myanmar.
If you need more accurate photos of them, please let me know.
