Marx S3 - Hood Warping?

I've got two, a Rock island and a AT&SF, and have been repairing and collecting for 10 years, and I've never heard of one warping like that.

Heat from attic storage?

Mike,

I thought that, too, but it's only in this one area. Even the motor, which isn't mounted (but needs repair - new brushes, reassembly, and what) shows no sign of excess heating.

Dunno if this would help, but I have a K-line S3 shell in ATSF in stock.   Contact info in profile.    

Thanks for the offer, let me mull it over. This Marx unit really is a project, though, and when I mean project what I mean to say is... it needs a whole lot of work, let me just say that. My original plan (don't laugh) was to convert it to semi-scale DC 2-rail, but since I have submitted to the siren song of 3-rail, I'm beginning to suspect that simply replacing the unit is in the offing. Still, I love the things heft. Gotta get one of these things running.

I don't think it was internal. Looks like the sun did that.  Attic heat would have warped the entire body.

Jim,

Looking at the shell again, I think it was definitely external now. Sun? Fireplace? Thermonuclear explosion? Who knows. Wish I had known about it beforehand, though.
