Note: During World War II almost perfect forgeries of Bank of England Pound notes were produced by prisoners in a German concentration camp. The enterprise was code named "Operation Bernhard". The following occur: 5, 10, 20 and 50 Pound notes with different dates, also including branch office issues such as Leeds and Bristol. They come with signatures of Catterns or Peppiatt. There are a number of very small but discernible differences between the Operation Bernhard counterfeits and genuine notes. For example, most counterfeits have a dull look in Britannia's eyes and less clarity on the cross at top of her crown. You can see other differences in the portrait of "Britannia".
