Some aspects of this topic are similar to the Where is Howland? and Where is Cape Belsham? threads [1], although the history behind Blackburne's observations is boring by comparison.
I have attached a plot of the position of 56 Hawker St worked by various methods. Blackburn's workings can be viewed at

From what I have read about cellnav I believe that Blackburne's observations can be considered accurate.
[1] Not the actual names of the threads.
