I have recently acquired another 0-4-0 which will be converted into another NWRR. However, after the disassemble, the main frame that holds the motor is difficult to get off. Not risking breaking the new porter, I'm leaving it on, and that means that the metal supports for saddle tank with still be in place. To disguise those, I'll make those into running boards. Sure, those are prototypical to the real thing, but its a compromise that makes somewhat makes sense.
