I have been looking for a Lionel M10000 set to restore. I want to find a low price, because I am going to strip it down and paint it Milwaukee Road colors. I found one at around $250, but it was rusty, and some of the rust looked like it had damaged the metal. Some others I found have parts missing, and some of the 753 and 754 cars have warped bellies. I assume the bellies are cast. What causes them to warp? Can they be straightened by heating them up and tapping them back to shape?
Thanks,
George
