I found a ring many, many years ago in the Tampa, FL area
. It has a cross in a crown, and decorative engraving on the sides. Inside is an engraving...RBP 103 to ... I will leave it to the rightful owner to identify the inititals of the recipient.
Interesting. Could the initial RBP 103 be the initials of the local "chapter"? If so, I wonder if there is any way to contact them to make inquiries. After all, the Knights Templar are a rather secretive society.
