Yes, N- Scale is hard to find and it's very very expensive. I've some old N material (early 80's), It was produced by "Lima". Nowadays, in Italy we can find some different N producers, like: rivarossi, RoCo, Fleischmann "piccolo", Peco and ACME.
About the coaches showed in the photo:
Left coach Type is "UIC-Z1", operating in those colours since 1985 until 1988, when it has benne painted like the right one. The Right coach showed is the "UIC Z 1975", operating since 1975. It has had those colours (double gray & yellow lines) since 1988 until 1994.
Both coaches are still in service like "Intercity" & "Eurocity".
Pleased to have been of help!!
