P = Post Brenhinol

Royal Mail in the Welsh language. This inscription can be found cast on to Bantam boxes and the large Meter boxes provided for business use, it is also seen on Garage boxes and Supermarket boxes. Since 1952 the sensitivities of the Scots have been recognised by replacing the EIIR cipher on letter boxes with the Scottish Crown for boxes erected in that country, but it wasn’t until c.2002 that boxes specially intended for the principality were produced.
