Thanks all,
And thanks Robin!
Do you currently have one or more of these vehicles?
I'll post a picture soon. As to the truck's history, I don't know much, but BATUS seems the most likely. It is left-hand drive if that's any indication.
Corrosion is definitely the main threat here. My truck is currently in good shape that way but I'm worried about the cab. Everything rots before your eyes (except 6061 aluminum). I have some strategies to combat rust, but it requires extreme vigilance. Lanolin based coatings are pretty effective if you stay on top of it. I have a big shop but this beast can't live in there, the door is a mere 11' high, and the crane is too tall.
Maybe a little Bedford barn would be the thing.
