Earlier this week I was in Bradford on Avon for a few hours. I remembered a conversation from about 45 years ago which suggested there might be an Edward VIII post box somewhere in the town. Unsurprisingly, I failed to find it, and a quick online search that evening showed I wasn't looking for quite the right thing; it is the Post Office building itself, now taken over by another retailer, which carries the cypher, much higher up than I was looking.
Apparently there are 100 or so Edward VIII post boxes known to exist, and although I'd never knowingly seen one, it turns out I have a picture of one. A couple of years ago I stayed for a week in an apartment in the red house on the harbour front in Tobermory, with the rare box just a few yards away:

Zooming in, the box can be seen just to the right of the RNLI flagpole, next to a red lifebelt mounting:

Wikipedia supplies the image I should've taken myself:
