Lovely banknote, the last Special run with a very low serial number. The note is NOT from from the Debden C146 where the serial numbers were from 001001 onwards to 002000. This note is from an extra print run of 1000 released in loose leaf form. This note is exceedingly rare as thus. Very rare indeed. These notes are so hard to find.  Wonderful prefix and a superb addition to the collection.
