mellers: I pop by here every so often to see how things are progressing, but we're no closer to being able to access the answers for this multi. In addition, I've also spotted that this listed building is now to be converted in to private dwellings. This means that whenever it is finished it's not going to be easily accessed by members of the public any more.
I think I have no choice but to archive this cache - my first one that I've had to say goodbye to. Shame [;)]. Thanks to everyone who visited and at least it opens the area for a new hide.
