The most interesting bit was the second date of issue for £50 and £100 notes for the Bank of Ireland: 3 November 1930. These notes were likely never issued, but their production was advanced enough for them to have had numbers allocated, listed following.
The information on the Munster & Leinster Bank has been known since the1990s, from Central Bank of Ireland sources, much of the rest is new.
All notes are dated 6.5.29, except for the second Bank of Ireland date on £50 and £100 notes: 3.11.30.
