Hi guys, in the future I want to make some modifications on Plarail/Tomy engines such as Murdoch, Gordon, Arthur, Spencer, Rebecca etc and turn them into their British Railways counter parts, such as the A1, A3, A4, 9F and Battle of Britain Classes. Now in order to do this I know I will have to make minor modifications to the chassis and bodies of the trains, but a major question I have is where do you get spare smokebox doors from. I was looking at Hornby ones but I'm not sure if they're big enough for Plarail engines. Any help?
