Wow, many thanks Chris. The pics are great, far better than than I could have hoped for. Looking at them, I do have the urge to have another go at modelling it, mine was a very quick adaptation of an O9 kit that I happen to have a few of, but now I could be tempted to go for it properly, just need to find some time.
Your photos show a lot more detail on the Roanoke loco than I could find before and I can also see that I will definately have to have a better go at the tender.
The second photo, I found pretty interesting, the difference in loading gauge between the coach and the wagon is quite considerable. I'm quite surprised how wide the wagon is, but that is a bonus for a minimum gauge rather than miniature model.
Thanks again, these will be put to good use, don't hold your breath waiting for the results though, it might take a while
