Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I am in the US, correct.  Doesn't it use the same boiler as the Wilesco D21 regular piston-operated steam engine?  Wouldn't he just as easily be able to contact Wilesco to make the same type of build as all other T125's like yours?  I only say so because I've only owned Wilesco steam engines, the D2 and the D14, and bought several spare parts from them too.
