The A1024 label must have been in situ for many, many, months (if not years) for the handwriting to be weathered away. Whatever the defect, it was not deemed as requiring immediate rectification.
Perhaps now, with the absence of a fitted CBT (assuming that one needs to be fitted to that pole for the native FTTP roll-out), whatever work that is required will be actioned. (If the A1024 label is still valid.)
