The first step in constructing this model was to prepare the main body. There were some small bits of flash here and there. I also found three cylindrical pieces inside the body near the corners. These are shown in the photo below. They must be left over from the manufacturing process, because they are in the way of the underframe. I cut them loose by first cutting near the bottom of the cylinder using a sprue cutter, and then cutting along the length of the cylinder against the body. They can then be removed without damaging the body.

Removing the flash from the round windows in the body was a bit more challenging. The flash in the end walls' windows came out very easily, but the ones in the side walls were very thick. They required quite a bit of careful cutting. The concern here is to make sure the windows maintain their roundness, because what you are left with is the final shape of window; there are no window panes to cover any miscuts. I found using a #11 blade and continuously circling the windows from the inside, out, worked well.
