To the best of my knowledge George V postboxes don't have a numeral. This is located a Corporation Square in Belfast.
Corporation Square extends from Corporation Street to Donegall Quay. The Victoria Channel runs just beyond the buildings at bottom of the street. It was originally named Ritchie's Dock after pioneer shipbuilder William Ritchie who came to Belfast from Ayrshire in 1791 and launched his first ship in the city in 1792 but the dock was actually constructed in the 1784.
