Photo can be enlarged quite a bit.

A wreck photo showing some underbody detail and the "B" end.

Is it possible that the side panels were added to this car after it was built?

Yes. Those are the Union Metal Products replacement sides with integral stakes. You'll notice that each stake looks like an I beam; they are actually the edge of the pressed panel bent outward with a second bend to form the flange. After each pair of sheets were fitted and riveted in place a weld bead was run on the edge both inside and out to unify the bent flanges into a structural member. The Accurail panel side car models this construction.
