1945 is a very rare year for the £20 note, with only three dates.
I've only ever seen this one:

Ireland, Twenty Pounds 1945.
Has anyone seen any of the other 1945 dates?
On irishpapermoney.com the list of recorded dates is growing, slowly. The £1 notes were completed a couple of years ago, but the other denominations have gaps. The goal is to have an image of every date.
If anyone has any of the missing notes, could they post a scan here on the forum, or send a scan to: lists AT irishpapermoney DOT com
