5 pounds (US$1.85), JUNE 2011. Like above note, but with windowed thread on front of note.
Curiously, all denominations of the new designs issued on 24 July 2011 had the windowed thread on the back, apparently to help distinguish them from the preceding issues. However, it now appears that the bank is reversing course. It remains to be seen if the thread will move to the front on the other denominations in this series.
