Ulster Bank £5 note entry 1907-1918 needs to be altered to 1907-1919. I added in the date 2 June 1919 to the list of dates, and will upload a picture shortly of a 1919 note. This one is interesting, as it is the latest date for an ulster Bank note with branches listed on it.
See this page on the Ulster Bank notes 1907-1919 for reference, and a picture of a 1919 note is on this link: https://www.irishpapermoney.com/old-irish-bank-notes/ulster-bank-pre-partition/ulster-bank-1852/ulster-bank-1919-Type-I.html
Although the 1919 is a different variety, SCWPM lists all the notes in the 1907-1919 dates together under p383.
