CIE published "Cuisle Na Tire", Vol 1 no 1 January 1945, the last one I have is May 1949
"CIE Weekly News" seems to have been running at the same time, Vol 3 No 2 is 11th June 1948, , vol 5 no 4 is August 27th 1948 and Vol 10 no 8 is 21st October 1949, how they got to Vol 16 on your scan of the Enterprise in 1950 suggests strange numbering!
(I attach a scan of CIE Weekly News Vol 5 no 4, August 27th 1948 which states under the header... and issued as a supplement to CIE readers of Cuisle Na Tire.)
"The Link" appeared in 1950?, I have 1952 issues Vol 3 no 1 January 4th, No 2 January 11th, No 3 January 18th
"Nuacht" was launched in October 1960, I think it ran to around 2003?
I'm fairy sure there are copies in the IRRS at Heuston.
