Does any-one know if the Irish Army used the British metal 12mag tin for the 30rnd Bren mag and if so does any-one have an example which they know to be ex Irish Army? I am speculating that they did use them and if so did they purchase 2nd hand U.K. examples or did they have brand new ones made when they purchased their Brens in the 1950s? I am especially interested to see how they marked their tins. Thanks for any info.
