Modelling the Irish scene has historically presented a challenge, particularly if you're doing it in Ireland. It is only in the last 15-20 years that things have become easier in terms of stock, kits and all the rest. For that we have the Internet to thank - it's that much easier to order what you're after, and information about what's available is more accessible.
I remember first coming to Dublin back in 1988, during an unemployment peak, and only ever seeing one model shop (Murphy's) in the whole place. It sold British-outline stock; I don't remember seeing anything in CIE/IE/IR livery there at the time. My parents took me around much of Ireland that year, and I never saw another model shop. The economic situation back then focussed people's minds on emigration, not modelling.
I think TMD kits (now SSM) existed back then, but actually getting hold of any was a challenge. They were not very well publicised in Britain, if at all.
Today, things are that much better materially, thanks to the Celtic Tiger, even if it did have a propensity to prowl around on quicksand. The very fact that this Forum exists to showcase what's being done demonstrates how much Irish modelling has developed out of almost nothing.
I'm just after turning 41. I've been in model railways in one form or another since the age of 5; dead-scale Scalefour since 1990, but modelling 5'3" (21mm gauge) only started this year. Just after realising that if/when I finish this "S" class, I'll have no 21mm gauge track to run it on
Since I no longer have youthful good looks, I resorted to radical plastic surgery and now look like this:
