As with Galteemore, the "gauge" description doesn't fit my Irish modelling which is in 2mm finescale.
So 1:152 on 10.5mm gauge track, which, at the risk of sounding elitist, is a long way from N Gauge.
I've also got a passing interest in 3mm scale on 9mm track to represent the narrow gauge, this interest is latent at the moment though as I've enough to be going on with!
