Sorry to be coming to this thread so late @jhb171achill. It is very informative indeed. There is definitely more interest in the periods that you describe in the thread. I don't know how many modelers 'young' or old, though I suspect that the 'younger modelers' you refer to may be more familiar with the post Supertrain era and may not associate with the grey 'n' green era through nostalgic reminiscences or familiarity with the rolling stock of that time. perhaps the number of replies to the thread is indicative, I'm not sure. Sadly there is a paucity of models from the period that are readily available (yes, they can be modeled by those already familiar with the period). In contrast, the UK market still has a a strong showing in the pre-grouping era with many models of the rolling stock of the GWR, LMS etc. Possibly the long awaited early versions of the 121 class or the 'you never know' A classes might help instill a little more interest in the earlier eras, may with some rolling stock to follow. Fingers crossed, I suppose. Thanks again for the thread. Kevin
