So to summarise:
We don't have any verifiable statement anywhere in this thread or linked sites that there actually is one in SE1 - all we have is Harry's original post that he had heard there was one "on the South Bank".
An article, which happened to be published in "In SE1" states that there are two in Southwark, but does not give a source other than directing us to the website of the Letter Box Study Group.
From a post I have found in the Greater London Industrial Archaeological Society Newsletter
in 2002, it appears that one of these could be in Nunhead Lane SE15.
From what I have now discovered of letter box history, and what I know of Southwark's building history, I suspect that the box is close to an area that was new residential development in 1936.
This makes me suspect that if we are to find the letter box in north Southwark, we should concentrate our search on the LCC estates built off Rotherhithe Street in the mid 1930s.
