a "p" before 14k on a wedding band

Hello
I need to sell an old wedding band but want to be sure it is not plated. This was the wedding ring of the grandfather of a friend of mine so it is quite old.

There is a "P" inside what looks to be the outline of a bell before the 14k stamp. Any help I would really appreciate it !
