Royal Crest
Sadly, I failed to do research about the Royal Crest pottery due to a lack of information. The company was established in the mid-20th century, but specific details about its founding and early history are not widely known.
Based on my preliminary research, it appears that ‘Royal Crest’ was the trade name of a certain porcelain manufacturer.
I listed some marks from my collections.

I will update if I find any other information.
