There have been more than a few blogs hereabout on various matters relating to postboxes – alternatives use; additional insignia; Queen Elizabeth; old; older; and, oldest.
This postbox, as manufactured in Cork, is likely to have seen service in Ireland. It currently resides in the Bunratty Folk Park where we spent a very pleasant and pleasurable afternoon on Easter Saturday. I do recommend a visit.
There is a second box in the village section of Bunratty – another red box; Victoria Regina; but a Penfolds postbox, similar to Skibbereen.
