An interesting choice.
For me it highlights the difficulty Rubicon must have. The Matilda I completely support (I wouldn't mind seeing the earlier A11 Matilda as well). The Scammel also looks like it would make a terrific model. However I think Rubicon must wonder at the size of the market for it. If this scale is to support 28mm models in the wargaming community I don't think tank transporters of any type are going to find much use. I don't want to discourage any particular kit from appearing but feel Rubicon should prioritise vehicles, in all their variations, that appeared in the front line.
