The big difference Larry is that the doors and hence the steps are at the ends, and it hasn't helped that I have had to narrow the coach sides to allow for the ends having been etched as if they were flat, rather than angled. It's all trial and error, with a bit of suck it and see. It is marketed as a scratch aid and there's definitely a lot scratching, mostly of my head. I very much doubt that anyone would do a proper kit and even less for a RTR pair. At the end of the day I will at least have something that may not be 100% accurate, but will hopefully look the part and will be representative of rolling stock that spent a lot of time on the Devon and Cornwall border.
