That's what I thought. Not only is it lower than most, but the combination of wide-spaced ribbed sides, narrow-spaced wide-ribbed ends and corrugated roof seems a little unusual. And I don't have the slightest idea what the door end looks like!
Unless someone volunteers to create it, it will probably remain unmodeled. I don't have the skills, or software to design it, even if I did know what the other end was like. Of course, I doubt that anyone ELSE knows what it looked like, so a standard door design would probably be fine.
