Well, this isn't much of an update, I'm waiting for answers from Archives and Universities
and it will take some time (to anyone checking this thread).
Suffice to say, I have contacted them all and received "the first answers"...
then we shall see what becomes of it.

There is a recording at probably a few places, no copies are lent or sold,
a visit was recommended.
I can't say I'm travelling to Ireland on a yearly basis,
- maybe I will arrange an archive visit ?

The same kind of archive journeys would be best for those in the states,
but I couldn't find a travel company that arranged this in a proper way.
