Hawky,
I have no idea where it's being produced, but I seem to recall Eastern Europe being mentioned some time ago, or, maybe it was Poland!! (Age is affecting the noggin, mate - sorry). I can't imagine that it would be shipped all the way from Japan purely for the Irish market, but who knows how the crazy world of consumerism really works. If I recall MLC knew something about it, and may have had a thread about it somewhere, or, at least, thrown a nugget into someone else's thread.
As for the codes on packaging, once again, MLC definitely had some info on those - I seem to remember a discussion about 'batches' and changes in the tobacco (it has 'softened' over the years), and in particular a noticeable change that seemed to happen overnight.
Of course this all may just be in my head......so, drop MLC a line, he's the font of knowledge on all things Condor.
