Hi, I've been planning an Avonside 0-4-0st for a layout of mine, and I cannot find any drawings that describe it. However, there is a very similar locomotive, Trojan, which looks like it may be either a sister class following the same rough dimensions, or indeed a member of the same class. There are some dimensional discrepancies, such as the length of the running plate beyond the cylinders, and, of course, the saddle tank. Other than that, they appear to be incredibly similar, almost identical. I'm almost comfortable with using these plans and modifying the tank. Does anyone know if they are of the same design, or, perhaps, if there are drawings of this class in a book I could buy?
