The shells on TMs that I am familiar with are aluminum skins bonded to shaped closed cell foam.
There was more wood used in earlier models but I don't know if any was used in the roof.
I am no expert, but either something heavy fell on the roof or, and I can't picture how, the rear shell was pressed in from the sides to cause the longitudinal crease that runs all the way under the other shell.
You obviously like a challenge.
