I hope the model does really well but it does strike me as a slightly unusual choice. It is really too big for any 'light railway' purposes or the traditional tightly curved shunting / industrial yard schemes that are popular in 0.
It would be interesting to know why this one was chosen above the smaller Kerr Stuarts 0-6-0T of similar design. I'm no expert but I know there was an 'Argentina' class with a much smaller boiler (mainly for export?) and a slightly smaller 'Triana' class that was ordered (but never delivered) for the Selsey Tramway.
I'm still hoping for an RTR Manning Wardle I or K (small, beautiful engines!). I suppose I should just start building one and then Dapol or Minerva will definitely bring one out...
