I have noticed that many of Lionel's Pre War Electric Locomotives like the No 38 and No 50 have sort of a "Sad Sack" look to them, bowed in the middle and sagging on the ends. Since both the body and chassis are stampings and not subject to warpage like the die cast locos, I'm wondering what causes this distortion to occur. I don't own one but have considered buying one. Can it be "straightened out" without doing a complete restoration and re-paint ?
