You are correct, the entire wall structure is upside down.
There is no stud to tube connection between the walls and the rest of the
structure. It is held in place by four internal pillars that also hold the roof
on.
(...) I never understood this building technique. Are the walls (the parts with the windows) just wedged upside-down? --Jeff (21 years ago, 1-Mar-04, to lugnet.trains)
