I have always understood that post boxes had the initials of the reigning monarch on them according to their date of installation. This one on the corner of Wigram Road appears to be different. There is some lettering on the base which I can't read but I do not think it's what I'm looking for. It has a small posting slit which I understand was common in the Victorian era as envelopes were smaller but apart from that no clues. Any information welcome.
