What company has a crown and also an olive branch crown?

I have a pendant that is silver or silverplated. It has a hallmark that is really tiny and hard to see, but it looks like a crown (like a British crown that would have the red velvet 'cap' as well as the crown) and under the crown is what looks like the letter P in a very scrolly font, and these are partially surrounded by what looks to be an olive branch crown, as in the days of the Olympics.

Can you help me with the maker? I'm sure this isn't old or valuable, but I'd like to identify the maker anyway. Thank you!
