Then they'd have just stolen a hunk of dead scrap metal. The only parts of him that were still salvageable were his wheels, pistons, motion, and frames. Everything that made him alive was gone, destroyed, wrecked beyond fixing.
Because he was badly damaged and beyond repair, no money was used or saved to mend him.
For that, he was permanently put in the back of the shed where his parts were stripped and used as spare to mend the other mountain engines.
If you read the Mountain Engines book, Culdee mentioned that Godred got smaller and smaller until there was nothing left as time went on.
I agree with you. Have you seen any of those automotive restoration shows? The guys on those programs are good at resurrecting machines people left to rust. And even if they can't restore something completely, they just make the machines into something else that still works in another way.
